The master mix facilitates reaction setup, and improves the reproducibility of experiments.This product is an improved version of Realtime PCR Master Mix (Code No. QPK-101). In particular, reaction specificity and PCR efficiency is enhanced.Features-High specificityThe specificity for the detection of low-copy targets is improved.-Homogeneous amplificationThe dispersion of PCR efficiency between targets is reduced by a new PCR enhancer*. (*Patent pending)-Broad dynamic rangeHigh specificity and effective amplification enable the detection of a broad dynamic range.-Compatibility for various real-time cyclers.The reagent is applicable to most real-time cyclers (i.e. Block type and glass capillary type). Because the 50x ROX reference dye is individually supplied with this kit, the kit can be applied to real-time cyclers that require a passive reference dye.-Hot start PCRThe master mix contains anti-Taq DNA polymerase antibodies for hot start technology. The antibodies are easily inactivated in the first denaturation step, thereby activating the DNA polymerase.About the fluorescent probe detection systemThe TaqMan® probe system utilizes fluorescence emission from the probes. The probes hybridize to the target amplicons and then emit fluorescence upon degradation by the 5'-3' exonuclease activity of Taq DNA polymerase. This type of detection system can achieve higher specificity in real-time PCR assays than the SYBR® Green I detection system.This kit includes the following components for 40 reactions (QPS-101T) and 200 reactions (QPS-101), with 50 μl per reaction. All reagents should be stored at -20°C.<QPS-101T>THUNDERBIRD™ Probe qPCR Mix 1 ml x 150x ROX reference dye 50 μl x 1JAPAN CHINATOYOBO CO., LTD.

For longer storage, this reagent should be kept at -20°C and protected from light. No negative effect was detected by 10 freeze-thaw cycles of THUNDERBRID™ Probe qPCR Mix. This reagent does not contain the ROX reference dye.-50x ROX reference dye can be stored, protected from light, at 2-8°C or -20°C. For real-time cyclers that require a passive reference dye, this reagent must be added to the reaction mixture at a concentration of 1x or 0.1x. The master mix solution with the ROX reference dye can be stored, protected from light, at 2-8°C for up to 3 months. For longer storage, this reagent should be kept at -20°C and protected from light. The pre-mixed reagents can be prepared according to the following ratios. [5] Table 1 shows the optimal concentration of the ROX dye.1x solutionTHUNDERBIRD™ Probe qPCR Mix : 50x ROX reference dye = 1.67 ml : 66.8 μl THUNDERBIRD™ Probe qPCR Mix : 50x ROX reference dye = 1 ml : 40 μl0.1x solutionTHUNDERBIRD™ Probe qPCR Mix : 50x ROX reference dye = 1.67 ml : 6.7 μl THUNDERBIRD™ Probe qPCR Mix : 50x ROX reference dye = 1 ml : 4 μlFor real-time cyclers that do not require a passive reference dye, THUNDERBIRD™ Probe qPCR Mix without the ROX reference dye can be used.1. Primer conditionsHighly sensitive and quantitative data depend on primer design. The primer should be designed according to the following suggestions;-Primer length: 20-30 mer-GC content of primer: 40-60%-Target length: ≤ 200 bp (optimally, 80-150 bp)-Melting temperature (Tm) of primers: 60-65°C-Purification grade of primers: Cartridge (OPC) grade or HPLC gradeNotes:-Longer targets (>200 bp) reduce efficiency and specificity of amplification.-Tm of the primers can be flexible, because the Tm value depends on the calculation formula.JAPAN CHINATOYOBO CO., LTD.

Fluorescent probeThe probes should be designed according to the guidelines of each probe system. Because insufficiently purified probes may inhibit the reaction, HPLC-grade probes should be used.The following DNA samples can be used as templates.1. cDNANon-purified cDNA, generated by reverse transcription reactions, can be used directly for real-time PCR using THUNDERBIRD™ Probe qPCR Mix. Up to 10% of the volume of a cDNA solution can be used for a real-time PCR reaction. However, excess volume of the cDNA may inhibit the PCR. Up to 20% (v/v) of the cDNA solution from ReverTra Ace® qPCR RT Kit (Code No. FSQ-101) can be used for real-time PCR (see [6]).2. Genomic DNA, Viral RNAGenomic DNA and viral RNA can be used at up to 200 ng in 50 μl reactions.3. Plasmid DNAAlthough super-coiled plasmids can be used, linearized plasmid DNA produces more accurate assays. The copy number of the plasmid DNA can be calculated by the following formula.Copy number of 1μg of plasmid DNA = 9.1 x 1011 / Size of plasmid DNA (kb)JAPAN CHINATOYOBO CO., LTD.

PCR cycling conditionsThe following table shows the recommended thermal conditions using primers designed according to the recommended primer and probe conditions described in [3]. Almost all targets can also be amplified using the ongoing conditions with other real-time PCR reagents.*1Due to the anti-Taq antibody hot start PCR system, the pre-denaturation can be completed within 60 sec. The pre-denaturation time should be determined according to the recommendations of each real-time cycler. If the optimal pre-denaturation time cannot be determined, the time should be set at 60 sec.Table 2 The recommended pre-denaturation time for each real-time cycler Real-time cycler Pre-denaturation time High speed cycler (e.g. Applied Biosystems 7500Fast) 20 sec Capillary cycler (e.g. Roche LightCycler™ 1.x, 2.0) 30 secGeneral real-time cyclers (Applied Biosystems 7700, 7500,7900HT (normal block), Stratagene cyclers, BioFlux cyclers 60 sec *2The following table shows the optimal denaturation times for each real-time cycler.

The extension temperature should be set at 56-64°C. *4If the target size is smaller than 300 bp, the extension time can be set at 30 sec on almost all real-time cyclers. Instability of the amplification curve or variation of data from each well may be improved by setting the extension time at 45-60 sec. Some real-time cyclers or software need over 30 sec for the extension step. In these cases, the time should be set according to each instruction manual (e.g. Applied Biosystems 7000/73000: ≥ 31 sec; Applied Biosystems 7500: ≥ 35 sec.).<3-step cycle> Temperature Time Ramp Pre-denaturation:95°C 20-60 sec *1Maximum Denaturation:95°C 1-15 sec *2 MaximumExtension: 60°C *3 30-60 sec *4 Maximum (data collection should be set at the extension step)JAPAN CHINA TOYOBO CO., LTD.

Inhibition by the components in thecDNA/DNA solution.-DNA: The DNA sample may contain PCRinhibitors. The DNA samples should berepurified.-cDNA: The components in the cDNA synthesisreagent may inhibit the PCR reaction. The cDNAsample should be used after dilution.The template DNA is insufficient. When the DNA/cDNA copy number is lower than10 copies per reaction, the linearity of the reactiontends to be lost. The template concentrationshould be increased.Adsorption of the DNA to the tubewall.The diluted DNA templates tend to be absorbedonto the tube wall. Dilution should be performedjust prior to experiments.Lost of linearity or lower signal in the lowDNA/cDNAconcentration region. Competition with primer dimerformation. In the probe assay, primer dimers are not detected. However, dimer formation may reduce the amplification efficiency of the target, especially for reactions at low template concentration. The reaction conditions should be optimized or the primer sequences should be changed.Loss of linearity of the amplification carves. Competition with non-specificamplification.In the probe assay, non-specific amplification isnot detected. However, non-specific amplificationmay reduce the amplification efficiency of thetarget. The reaction conditions should beoptimized or the primer sequences should bechanged.Inappropriate cycling conditions. Optimize the cycling conditions according to [5]. Degradation of the primers. Fresh primer solution should be prepared.The PCR efficiency is lower than 90% (slope:<-3.6) The calculation of the PCRefficiency is inappropriate. The Ct value on the linear region should be used to calculate PCR efficiency.The PCR efficiency is higher than 110%. The calculation of the PCRefficiency is inappropriate.The Ct value on the linear region should be usedto calculate PCR efficiency.Poor purification of the templateDNA.Low-purity DNA may contain PCR inhibitors.Re-purify the DNA samples.Absorption of the template DNA tothe tube wall.Diluted DNA templates tend to be absorbed ontothe tube wall. Dilution of the templateDNA/cDNA should be performed just prior toexperiments.Plasmid DNA or PCR product isused as a template.In general, plasmid DNA or PCR product is usedat low concentration. Diluted DNA templates tendto be absorbed onto the tube wall. Dilution of thetemplate DNA/cDNA should be performed justprior to experiments. Dilution with a carriernucleic acid solution (Yeast RNA) is alsoeffective in improving linearity.Inappropriate thermal conditions. Optimize the thermal conditions according to [5].Reproducibility is notgood.Low purity of the primers or probes.Different lots of primers or probes may showdifferent results. When the lot is changed, priortesting of the primer or probe should beperformed.JAPAN CHINATOYOBO CO., LTD.

Change the contaminated reagent.Amplification from the non-template control(NTC). Inappropriate settings offluorescence measurement, such asin the case of multiplex PCR. In multiplex experiments, inappropriate setting of fluorescence measurement may cause the detection of noise by the cross talk of fluorescent dyes. Settings should be reconfirmed.Excessive amount of ROX reference dye. Excessive amount of ROX reference dye may cause low signal. 50x ROX reference dye should be used according to [5] Table 1.Inappropriate settings of fluorescence measurement. Settings should be confirmed according to the instruction manual of each detector.Low purity of fluorescent probes. Low purity of the probe may increase the baseline. HPLC grade probes should be used.Excessive intensity of the quencher Dye. Certain quenchers (e.g. TAMRA) may cause a higher baseline because of its fluorescence. Use of a non-fluorescent quencher may improve the high baseline.Degradation of the probe. Store the probes according to the manufacture’srecommendations.Insufficient fluorescence measurement time. Certain detection systems require a longer time to detect the fluorescent signal. Longer extension (measurement) time (45-60 sec) may improve the unstable signal.Low amplificationcurve signal /Unstable amplificationcurve signal.Insufficient reaction volume. Low reaction volume may cause an unstablesignal. Increase the reaction volume.JAPAN CHINATOYOBO CO., LTD.

用于工业与公共设施清洗的r几种脂肪醇乙氧基化物的性能研究

用于工业与公共设施清洗的r几种脂肪醇乙氧基化物的性能研究

用于工业与公共设施清洗的r几种脂肪醇乙氧基化物的性能研究吴霞【摘要】脂肪醇乙氧基化物非离子表面活性剂在清洗剂中常被用做主活性成分,带支链结构的脂肪醇醚产品相对于直链产品具有更强的去污力、更低的泡沫、更好的润湿性能和更低的凝固点.本文主要从基础应用性能方面,探究几种不同结构的非离子表面活性剂在润湿、泡沫、洗涤、硬表面清洗、耐碱和凝固点等方面的性能,并与常规的月桂醇乙氧基化物进行比较.希望对工业和公共设施清洗配方的设计有所帮助.【期刊名称】《中国洗涤用品工业》【年(卷),期】2018(000)005【总页数】8页(P58-65)【关键词】脂肪醇乙氧基化物;应用性能;工业和公用设施清洗【作者】吴霞【作者单位】沙索(中国)化学有限公司,江苏南京,210047【正文语种】中文【中图分类】TQ423.2工业洗涤剂是在工业化生产领域,由于生产技术上的需要而使用的洗涤剂,包括工艺用洗涤剂和非工艺用洗涤剂。

例如在机械加工工业中,对钢材的酸洗(除锈)、碱洗(脱油脂)属于工艺洗涤过程,对机械加工设备的清洗(使用金属清洗剂)属于非工艺洗涤过程。

但是用的洗涤剂都属于工业洗涤剂。

公用设施洗涤剂是适应人类生活社会化,从家用洗涤剂分化出来的一类洗涤剂,用于公用设施及社会化清洁服务。

其洗涤基质大都为有规则的硬表面,洗涤过程由专职人员来承担。

例如,承担社会清洁服务的洗衣房使用有别于家用织物洗涤剂的一类洗涤用品,承担建筑物清洗,宾馆、剧场、车站等公共场所的专业清洗公司,一般使用机械化方式和专用洗涤剂完成清洗工程。

服务行业中与洗涤有密切关系的如餐饮业洗涤餐具、厨具、灶具;医院中洗涤手术器械、病床用织物,手术前洗手消毒;公共场所洗涤厕所、卫生间,都需要较家用洗涤剂洗涤消毒性能更好的专用产品。

工业与公共设施清洗剂中使用的原料范围很宽,种类很多,这是因为工业及公共设施洗涤工艺中,面对的基质和污垢要复杂得多,洗涤现场千差万别,对洗涤剂的技术要求也参差不齐,但是使用频率最高的仍然是表面活性剂。

温度数据采集系统的设计与实现卞绍顺,王利华中国矿业大学信息与电气工程学院,江苏徐州(221008)E-mail:bianshaoshun@摘要:本设计的主要目的是实现实时温度数据采集。

在硬件上采用单片机AT89S52作为主处理芯片,通过温度传感器DS18B20对温度数据进行采集,将测得温度通过RS232串行接口标准送入计算机。

上位机使用VB中的MSComm控件实现与下位机通讯,并在VB界面上显示监测点的实时温度值、最大值、最小值和采集温度的个数。

关键词:温度数据采集;单片机;Visual Basic;串行通讯1 概述随着科学技术的进步,在生产和科学实验中,常常要测控很多参数,诸如温度、压力、转速等,通常的方法是使用专用的仪表人为观测、记录处理数据、做出判断。

然而,专用的这些仪表往往价格昂贵,外围电路比较复杂,测量精度受所选设备影响。

因而传统的检测与控制越来越适应不了社会的要求。

如何将计算机与各种设施、设备结合,简化人工操作并实现自动控制,满足社会的需求,成为一个很迫切的问题。

本文根据自己的实验所写,实现一种实时温度数据采集系统,对采集数据的远距离传输,由于单片机处理数据的能力不是很快,因此需要单片机跟其他数据处理设备(例如PC机)进行交换,设计实时监控系统能很好的解决这些问题。

2 温度采集系统组成系统分为两部分:实时温度数据采集终端(下位机)和通信控制软件(上位机)。

数据采集终端(下位机)主要由AT89S52、DS18B20、MAX232组成。

温度传感器DS18B20将被测环境温度转化成带符号的数字信号并传送给单片机,同时将信号进行编码传送给上位机。

通信控制软件(上位机)主要由微机、主控软件等部分组成。

上位机的控制界面采用Visual Basic6.0语言编写,上位机通过串口与下位机通信。

在VB6.0的控件工具箱中,提供了一个使用非常方便的串行通信控件MSComm,可以通过这个控件控制COM口进行通讯[2]。

下位机检测到现场温度数据,传送到上位机,上位机接收到数据,并对数据进行监测。

上位机可以接收下位机传输的不同的测量的值,并在监控界面中显示出来,使用户能够看到现场测量温度的数值变化情况。

3 下位机系统的硬件设计下位机部分主要由温度传感器、单片机等组成,在现场采集温度信号,并将温度信号转换成数字信号,通过RS232接口标准传送给上位机。

温度传感器DS18B20的输出线与单片机AT89S52的P3.3口相连。

AT89S52的输入端RXD和输出端TXD分别从芯片的10口和11口引出,并与MAX232的输出口12和输入口11相连。

MAX232的输出口14和输入口13分别与DB9的输入口2和输出口3相连。

实现下位机AT89S52与上位机PC的连接。

硬件电路图见图1图1温度数据采集系统原理图通过这个电路我们便可以实现温度的采集、传输、以及在上位机上的显示,使用户能够清晰的了解现场温度的变化。

实际做出的电路板如图2图2温度数据采集系统下位机3.1单片机的选择单片机选择AT89S52,它是一个低功耗,高性能CMOS 8位单片机,片内含8k Bytes ISP(In-system programmable)的可反复擦写1000次的Flash只读程序存储器,器件采用ATMEL公司的高密度、非易失性存储技术制造,兼容标准MCS-51指令系统及80C51引脚结构,芯片内集成了通用8位中央处理器和ISP Flash存储单元,功能强大的微型计算机的AT89S52可为许多嵌入式控制应用系统提供高性价比的解决方案[3]。

单片机的程序设计采用汇编语言,用查询方式采集温度数据,并进行数据处理。

考虑到现在PC机很少带有串口,加上了USB口,当然程序要变的更为复杂。

3.2温度传感器的选择DS18B20是DALLAS公司生产的一线式数字温度传感器,具有3引脚TO-92小体积封装形式;温度测量范围为-55℃~+125℃,可编程为9位~12位A/D转换精度,测温分辨率可达0.0625℃,被测温度用符号扩展的16位数字量方式串行输出;其工作电源既可在远端引入,也可采用寄生电源方式产生;多个DS18B20可以并联到3根或2根线上,CPU 只需一根端口线就能与诸多DS18B20通信,占用微处理器的端口较少,可节省大量的引线和逻辑电路。

以上特点使DS18B20非常适用于远距离多点温度检测系统。

3.3 其他器件选择MAX232是由德州仪器公司(TI)推出的一款兼容RS232标准的芯片。

由于电脑串口RS232电平是-10v +10v,而一般的单片机应用系统的信号电压是TTL电平0 +5v,MAX232就是用来进行电平转换的,该器件包含2驱动器、2接收器和一个电压发生器电路提供TIA/EIA-232-F电平[4]。

该器件符合TIA/EIA-232-F标准,每一个接收器将TIA/EIA-232-F 电平转换成5-V TTL/CMOS电平。

每一个发送器将TTL/CMOS电平转换成TIA/EIA-232-F 电平。

4 上位机软件设计上位机的控制界面采用Visual Basic6.0语言编写,通过COM口与下位机连接。

将监控到的温度数据在监控界面中显示出来,使用户能够直观的了解到现场温度变化,并能够保存采集到的温度数据。

而VB在程序界面设计、多媒体开发方面更是独具优势。

因此特别适合初学者和业余人员使用。

4.1 VB环境下串行通讯的方法VB中的MSComm控件是Microsoft公司提供的Windows下串行通讯编程的ActiveX控件。

在VB工具工具栏里面打开工程,选中其中的部件,再在部件里面的控件栏里选中Microsoft Comm Control 6.0 图形如图3。

在VB中的图标见图4。

MSComm控件通过串行端口传输和接收数据,为应用程序提供串行通讯功能。

图3 Microsoft Comm Control 6.0 图形图4串行通讯控件图标4.2 VB界面设计VB的设计界面包含5个Text文本框,2个Frame,4个Label,3个Command,一个Mscomm 控件和1个Time。

Text1显示的是当前接收数据的内容,Text2显示的是所有接收到的数据,Text3显示的是所有接收数据中的最高值,Text4显示的是所有接收数据的最低值,Text5显示的是所有接收数据的个数。

Frame1的内容是接收温度的最高、最低值,Frame2的内容是接收的温度数据。

Label1的内容是当前温度,Label2的内容是温度最高值,Label3的内容是温度最低值,Label4的内容是数据个数。

Command1的是接收按钮,Command2的内容是清空按钮,Command3是导出数据按钮以EXCEL形式表示出来[1]。

其中VB的程序编写比较简单,文章中就不介绍编程思想。

程序主界面如图5:图5上位机界面图6 EXCEL数据表上图中显示的是以EXCEL形式导出的数据图,当我们点击导出数据时程序便会以EXCEL形式将文本框中的内容表示出来,并保存到电脑中。

方便了我们对数据的统计分析,为以后的研究提供了方便。

5 总结本次设计达到了预期效果,但是其中还有很多地方需要改进,比如说在设计中没有实现多点同时测量,传输距离比较近等问题。

RS232接口是标准串行接口,其通讯距离小于15m,不能实现数据的远距离传输。

这样大大限制了它的应用范围,为弥补RS-232之不足,电子工业协会(EIA)制订RS-422串口标准,将传输速率提高到10Mb/s传输距离延长到1000M (速率低于100kb/s时),并允许在一条平衡总线上连接最多10个接收器。

这样就可以实现数据的远距离传输,使得温度数据采集系统应用的范围更加广泛。

这些都需要在以后的设计中进一步完善。
