果胶酶活性检测试剂盒说明书微量法

果胶酶活性检测试剂盒说明书微量法注意：正式测定之前选择2-3个预期差异大的样本做预测定。

货号：BC2635规格：100T/48S产品内容：提取液：液体100mL×1瓶，4℃保存。

试剂一：液体25mL×1瓶，4℃保存。

若溶液中有不溶解物质，可以50℃水浴溶解。

试剂二：液体20mL×1瓶，4℃避光保存。

标准品：粉剂×1支，10mg半乳糖醛酸。

临用前加入0.943mL蒸馏水，配成50μmol/mL的标准液产品说明：果胶酶（pectinase）是分解果胶的酶类，包括原果胶酶，果胶酯酶，多聚半乳糖醛酸酶和果胶裂解酶四大类，广泛存在于高等植物果实和微生物中，是水果加工中最重要的酶。

果胶酶水解果胶生成半乳糖醛酸，半乳糖醛酸与DNS试剂反应生成在540nm有特征吸收峰的棕红色物质，测定540nm处吸光值变化可计算得果胶酶活性。

试验中所需的仪器和试剂：可见分光光度计/酶标仪、台式离心机、水浴锅、微量玻璃比色皿/96孔板、可调式移液枪、研钵/匀浆器、冰和蒸馏水。

操作步骤：一、粗酶液提取：组织：按照组织质量（g）：提取液体积(mL)为1：5~10的比例（建议称取约0.1g组织，加入1mL提取液）进行冰浴匀浆，然后10000g，4℃，离心10min，取上清置于冰上待测。

菌类：按照细胞数量（104个）：提取液体积（mL）为500~1000：1的比例（建议500万细胞加入1mL 提取液），冰浴超声波破碎细胞（功率300w，超声3秒，间隔7秒，总时间3min）；然后10000g，4℃，离心10min，取上清置于冰上待测。

液体：直接检测。

二、测定步骤：1、分光光度计/酶标仪预热30min以上，调节波长至540nm，蒸馏水调零。

2、将50μmol/mL标准液用蒸馏水稀释为10、8、6、4、2、1μmol/mL的标准溶液备用。

3、取40μL样本沸水浴10min备用。

4、操作表：(在1.5mL离心管中)对照管测定管标准管空白管试剂一（µL）20020020020050℃水浴温育5min标准溶液（µL）--40-样本（µL）-40--蒸馏水（µL）---40煮沸样本（µL）40---混匀，50℃水浴反应30min，马上沸水浴5min，冷却后8000g，常温离心10min，取上清。

合成方法二
NaHMDS (85 mL, 2.0 M) was added dropwise to a solution of 2-phenylacetonitrile1(7.96g) in THF (300 mL) under cooling in an ice-salt bath. The mixture was stirred for 2 h, then R-(−)-epichlorohydrin2(7.548 g) was added dropwise (3 h, 0 °C). Stirring was continued for 2h at 0°C then overnight at room temperature. The reaction solution was then cooled on ice, and a small amount of water was added. The resulting mixture was concentrated under reduced pressure, then ethanol (100 mL) and 1.5 N/KOH aqueous solution (100 mL) were added to the residue. The obtained mixture was heated to reflflux for 8h. The reaction solution was allowed to cool to room temperature, and concentrated hydrochloric acid was added to adjust the pH to <2. This mixture was stirred at 0°C for 2h then was concentrated under reduced pressure. Ethyl acetate and water were added to the concentrated solution to carry out liquid separation. The organic layer was washed successively with a saturated sodium bicarbonate aqueous solution and a saturated sodium chloride aqueous solution. The organic layer was dried over magnesium sulfate, the drying agent was removed by filtration, and the filtrate was concentrated under reduced pressure. . The residue was purifified by silica gel column chromatography, giving the title compound3(9.96 g, 49.8% yield) as a white solid

高效液相色谱法测定注射用美罗培南的有关物质

第35卷第3期长治医学院学报2021 年 6 月JOURNAL OF CHANGZHI MEDICAI COLLEGE167Vol. 35 No. 3Jun. 2021高效液相色谱法测定注射用美罗培南的有关物质李金格禹玉洪**作者单位山西医科大学药学院药剂教研室(030001)* 通信作者(E-mail ：3024546064@ qq. com)摘要目的：探讨优化注射用美罗培南杂质A 、B 的测定方法。

方法：运用高效液相色谱法(HPLC) 进行检测，色谱柱以十八烷基硅烷键合硅胶为填充剂；流动相A ：20. 0 mmol-L'1磷酸二氢钠-甲醇(89 ：11, V/V)，流动相B ：甲醇，流速1.0 mL-min 1,检测波长220 nm,柱温30 P 。

结果：主成分峰与杂质峰可实现基线分离，杂质A 检测限和定量限分别为1. 62,5.15 ng,杂质B 检测限和定量限分别为0. 85,2. 51 ng ；1.2~24.0 ixg-mL -1的杂质A 具有良好的线性关系(r=0. 999 9) ,0.7-14.0 ixg-mL 1的杂质B 具有良好的线性关系(r=0. 999 9)；杂质A 平均加样回收率为101.2%(RSD= 1.38%,“ = 9),杂质B 平均加样回收率为100.2%(RSD=1.29%,n = 9)o 经破坏性试验，美罗培南可能的降解杂质A 、B 均不干扰美罗培南主峰的测定。

结论:检测限及定量限、精密度、稳定性、耐用性试验结果均符合HPLC 有关物质测定的方法学验证要求。

本HPLC 法专属性良好，可用于美罗培南的主要杂质A 、B 的定量控制。

Meth ods :Using the high performance liquid chromatography ( HPLC ) to detection , Octadecylsilane-bonded silica gel was used as the fi ler ； The mobile phase A : 20. 0 mmol * L -1 sodium dihydrogen phosphate-methanol ( 89 ： 11, V/V) . The mobile phase B : methanol ,the flow rate was 1. 0 mL *m in _1 and the detection wavelength was set at 220 nm. The column temperature was set at 30 % . Re sults :The principal component peak and impurity peak could achieve baseline separation. The detection limit and quantitative limit of impurity A were 1. 62 ng and 5. 15 ng respectively , and the detection limit and quantitative lim 让 of impurity B were 0. 85 ng and 2. 51 ng respectively. There was A good linear relationship between impurity A (r = 0. 999 9) and impurity B ( r= 0. 999 9 ) in therange of 1. 2-24. 0 |xg *m L _1 and 0. 7 ~ 14. 0 jig * mL -1. The average recovery of impurity A was 101. 2% ( RSD = 1. 38% , n = 9),and that of impurity B was 100. 2% ( RSD = 1. 29% , n= 9). After stressing test, both of impurities A and B of meropenem didn * tinterfere w 让h the determination of meropenem main peak. Conclusion : The test results of detection lim 让 and quant N ative lim 让，pre cision ,stabil 让y and durability all meet the methodological verification requirements of HPLC related substance determination. The HPLC method has good specificity and can be used for the quant N ative control of major impurities A and B.Key words meropenem ； related substances ； HPLC注射用美罗培南(Meropenem, C ”H25弘0申) 是由日本住友制药公司与英国ICI 制药公司共同开发的第二代碳青霉烯抗生素，通过干扰细菌细胞壁的合成发挥杀菌作用，具有广谱耐酶的特点[1_4]o 在美罗培南原料中常检测出杂质A 及杂质B,杂质A(C 17H 27N 3O 6S)为美罗培南四元内酰胺环结构发生水解反应而形成，系美罗培南的降解产物；杂质B(C 34H 50N 6O 10S 2)为美罗培南与杂质A 发生聚合反应而形成，系美罗培南的二聚体X 。

Amino acid N -terminal sequencing ， relative molecular weight analysis ， amino acid composition analysis ， protein purityanalysis ， endotoxin content ， dihydroxyphenylalanine （DOPA ） content of recombinant mussel adhesive protein were determined by the following methods ： Edman degradation ， matrix -assisted laser desorption ionization time -of -flight mass spectrometry （MALDI -TOF -MS ）， phenyl -isothiocyanate （PITC ）， nonreductive SDS -polyacrylamide gel electrophoresis （SDS -PAGE ）， gel method ， modified Ar⁃now. The efficacy of recombinant mussel adhesive protein was evaluated by cell migration and repairing effect of zebrafish tail fin. Re⁃sults showed that the obtained recombinant mussel adhesive protein was confirmed to be consistent with the theoretical primary structure ， protein purity of more than 95%， endotoxin <10 EU ·mg -1， DOPA content above 5%. When the recombinant mussel adhesive protein concentration was 60 μg ·mL -1， the effect of promoting cell proliferation was the most obvious ， and it had very significant activity （P <0.01）. The caudal fin area of zebrafish in sample group was significantly increased compared with model control group （P <0.001）. The results indicated that recombinant mussel adhesive protein can promote cell migration and repair healing and has the potential to be used as biomedical materials.Key words ：mussel adhesive protein ； gene recombination ； biological materials ； representation ； efficacy evaluation贻贝粘蛋白（mussel adhesive protein ， MAP ）也称作贻贝足丝蛋白（mussel foot protein ，Mfps ），收稿日期：2023⁃02⁃24；接受日期：2023⁃03⁃31联系方式：李敏 E -mail:*******************;*通信作者侯增淼 E -mail:***********************.cn李敏，等：重组贻贝粘蛋白的表征及功效评价是海洋贝类——紫贻贝（Mytilus galloprovincalis）、厚壳贻贝（Mytilus coruscus）、翡翠贻贝（Perna viri⁃dis）等分泌的一种特殊的蛋白质，贻贝中含有多种贻贝粘蛋白，包括贻贝粘蛋白（Mfp 1～6）、前胶原蛋白（precollagens）和基质蛋白（matrix proteins）等［1］。

菠萝蛋白酶检测试剂盒(福林酚比色法)

菠萝蛋白酶检测试剂盒(福林比色法)简介：菠萝蛋白酶(Bromelain)简称菠萝酶，亦称凤梨酶、凤梨酵素等，是存在于菠萝植株中的蛋白水解酶，可从菠萝果茎、叶、皮提取出来，经精制、提纯、浓缩、酶固定化、冷冻干燥而得到，菠萝蛋白酶已被广泛应用于食品、医药等行业。

利用吸附力、离子键、共价键等不同的联结方式，将酶与不溶性载体联结，制成固定化酶，可以很好的避免酶的失活，易于储存运输。

Leagene菠萝蛋白酶检测试剂盒(福林比色法)检测原理是通过蛋白酶催化底物酪蛋白，后者水解生成酪氨酸，酪氨酸含有酚羟基，可与福林试剂发生福林反应，即福林试剂在碱性条件下容易定量的被酚类化合物还原，生成钨蓝和钼蓝的混合物，呈现不同深浅的蓝色。

于分光光度计检测吸光度，以吸光度的大小与酪氨酸含量的多少有关，吸光度大说明酪氨酸含量高，也就是说菠萝蛋白酶分解的酪蛋白多，酶活性高。
