In-Fusion
Please read the In-Fusion HD Cloning Kit User Manual before using this Protocol-At-A-Glance. This abbreviated protocol is provided for your convenience, but is not intended for first-time users.Cloning more than two fragments at once (e.g, multiple inserts simultaneously into one linearized vector) requires adherence to specific considerations in experimental design and overall cloning protocol. This Protocol-At-A-Glance details these considerations and recommended modifications to ensure cloning success.Please note the following materials are required but not supplied:•Ampicillin (100 mg/ml stock) or other antibiotic required for plating the In-Fusion reaction •LB (Luria-Bertani) medium (pH 7.0) •LB/antibiotic plates • SOC mediumThe table below is a general outline of the protocol used for the In-Fusion HD Cloning Kits. Please refer to the specified User Manual pages for further details on performing each step.Table I. In-Fusion HD Protocol OutlineStepAction User Manual Pages2 Design PCR primers for your sequence(s) of interest with 20-bpextensions (5’) that are complementary to the ends of adjacentsequences (the linearized vector or another insert).6–8 3 Amplify your sequence(s) of interest with CloneAmp™ DNApolymerase. Verify on an agarose gel that your targets have beenamplified and confirm the integrity of the PCR products.8–9 4 Spin-column purify your PCR products OR treat with CloningEnhancer.Spin-Column Protocol I (p. 9–11) OR Cloning Enhancer Protocol II (p. 11) 5 Set up your In-Fusion cloning reaction:2 μl 5X In -Fusion HD Enzyme PremixX μl Linearized vectorX μl Each insertX μl dH 20 to a total reaction v olume of 10 μl. Mix well.6Incubate the reaction for 15 min at 50°C, then place on ice.I. PCR and Experimental Preparation (Section IV of the User Manual)A. Preparation of a Linearized Vector by Restriction DigestionFor vector linearization via PCR, please see primer design recommendations in the User Manual,Section IV.B.Complete, efficient digestion will reduce the amount of cloning background. Generally speaking, twoenzymes cut better than any single enzyme. Digestion efficiency will always be better if the restrictionsites are as far apart as possible.1.Incubate your restriction digest as directed by the restriction enzyme supplier. Longer reactiontimes can increase linearization and reduce background.2.After digestion, purify the linearized vector using a PCR purification kit. We recommend gelpurification using the NucleoSpin Gel and PCR Clean-Up kit (Cat. No. 740609.50).3.[Control] Check the background of your vector by transforming competent cells with 5–10 ng ofthe linearized and purified vector. If background is high, add more restriction enzyme(s) andcontinue digesting the vector (2 hr to overnight). Gel purify the remainder of the vector andtransform again.B. PCR Primer DesignWhen designing In-Fusion PCR primers, consider the following:1.Every PCR primer for multi-insert cloning must be designed in such a way that it generatesproducts containing 5’ ends with 20 bp of homology to the ends of the neighboring cloningfragments (either the linearized vector or other inserts).2.The 3’ portion of each primer should:∙be specific to your template∙be between 18–25 bases in length, with GC-content between 40–60%∙have a T m between 58–65°C; with the difference between the forward and reverse primers≤4°C. T m should be calculated based upon the 3’ (gene-specific) end of the primer, NOT theentire primer.∙not contain identical runs of nucleotides; the last five nucleotides at the 3’ end of eachprimer should not have more than two guanines (G) or cytosines (C)3.Avoid complementarity within each primer and between primer pairs4.Online tools are available to help with primer design:∙BLAST searches can determine specificity and uniqueness of the 3’ end (at/BLAST/)∙Our online primer design tool simplifies PCR primer design for In-Fusion reactions (at/US/Products/Cloning_and_Competent_Cells/Selection_Guides/Online_In-Fusion_Tools)5.Desalted oligonucleotide primers are generally recommended for PCR reactions. However,PAGE purification may be needed for primers of poor quality or longer than 45 nucleotides.C. PCR Amplification of Target Fragment(s)The In-Fusion method is not affected by the presence or absence of A-overhangs, so you can use anythermostable DNA polymerase for amplification, including proofreading enzymes. We recommend using our CloneAmp HiFi PCR Premix (included in every In-Fusion HD Cloning Plus system, and soldseparately as Cat. No. 639298). If you are using a different po lymerase, please refer to the manufacturer’s instructions. If using CloneAmp HiFi PCR Premix, please read the Protocol-at-a-Glance and follow the guidelines below:Table II. Recommendations for PCR with CloneAmp HiFi PCR PremixTemplate Type Template Amount Product Size Extension TimeE. coli genomic DNA 100 pg–100 ng up to 10 kb 5 sec/kbλ DNA10 pg–100 ng up to 15 kb 5 sec/kbPlasmid DNA 10 pg–1 ng up to 15 kb 5 sec/kbcDNA ≤ the equivalent of25–125 ng total RNAup to 6 kb 5–10 sec/kbWhen PCR cycling is complete, confirm your product(s) on an agarose gel.II. In-Fusion Cloning Procedure (Section VI of the User Manual)Both protocols below are appropriate for PCR that produces a single band of the desired size. If non-specificbands are visible on your gel, use Protocol I.A. Protocol I: In-Fusion Cloning Procedure w/Spin-Column Purification1.Isolate each target fragment (insert or linearized vector) by gel extraction followed by spin-columnpurification using a silica-based purification system, such as the NucleoSpin Gel and PCR Clean-Upkit.2.Plan the In-Fusion cloning reaction. Good cloning efficiency is achieved when using 50–200 ng ofvector and inserts, respectively. More is not better. Use the table below for reactionrecommendations.Table III. Recommended In-Fusion Reactions for Purified FragmentsRxn Component Cloning Rxn Negative Control Rxn Positive Control RxnLinearized vector 50–200 ng** 1 μl 1 μl of pUC19 controlvector5X In-Fusion HD EnzymePremix2 μl 2 μl 2 μlDeionized Water to 10 μl to 10 μl to 10 μl *<0.5 kb: 10–50 ng, 0.5 to 10 kb: 50–100 ng, >10 kb: 50–200 ng**<10 kb: 50–100 ng, >10 kb: 50–200 ngMolar Ratio RecommendationsGenerally, the molar ratio of each of the multiple inserts should be 2:1 with regards to the linearized vector, i.e., two moles of each insert for each mole of linearized vector. The molar ratio of two inserts with one vector should be 2:2:1. Specific exceptions are listed below:∙If an insert is large with respect to your linearized vector, we recommend a molar ratio of 1:1 ∙For cloning small DNA fragments (150–350 bp), the suggested insert-to-vector molar ratio is 3–5:1∙For cloning of short synthetic oligos (50–150 bp), the suggested oligo to vector molar ratio is 5–15:1. Depending on the oligo length, the optimal molar ratio must be determined empirically.3.Set up the In-Fusion cloning reaction:2 μl5X In-Fusion HD Enzyme Premixx μl*Linearized vectorx μl*Purified PCR insertx μl*Purified PCR insertx μl dH2O (as needed)10 μl Total volume* For reactions with larger combined volumes of vector and PCR insert (>7 μl of vector + insert), double the amount of enzyme premix, and add dH20 for a total volume of 20 μl.4.Adjust the total reaction volume to 10 µl using deionized H2O, and mix.5.Incubate the reaction for 15 min at 50°C, then place on ice.6.Continue to the Transformation Procedure (Section III). You can store the cloning reactions at –20°Cuntil you are ready.B. Protocol II: In-Fusion Cloning Procedure w/Cloning Enhancer Treatment1.Add 2 µl of Cloning Enhancer to 5 µl of each PCR reaction (insert or linearized vector).e a thermal cycler to incubate at 37°C for 15 min, then at 80°C for 15 min. If you used more than100 ng of DNA template, extend the 37°C incubation to 20 min. If you are using a water bath or heatblock rather than a thermal cycler, extend each incubation to 20–25 min.NOTE: If you cannot proceed immediately to the cloning reaction, store Cloning Enhancer-treatedPCR reactions at –20°C until you are ready.3.Set up the In-Fusion cloning reaction:2 μl5X In-Fusion HD Enzyme Premixx μl*Linearized vectorx μl** Treated PCR insertx μl** Treated PCR insertx μl dH2O (as needed)10 μl Total volume* Use 50–200 ng of linearized vector.** Use 1–2 μl of Cloning Enhancer-treated fragments, regardless of their length. The total volume ofCloning Enhancer-t reated PCR fragments should be up to 4 μl per 10-μl reaction. If you obtain a lowproduct yield from your PCR reaction, we recommend purification of PCR fragments instead ofCloning Enhancer treatment.4.Adjust the total reaction volume to 10 µl using deionized H2O, and mix.5.Incubate the reaction for 15 min at 50°C, then place on ice.6.Continue to the Transformation Procedure (Section III). You can store the cloning reactions at –20°Cuntil you are ready.III. Transformation Procedure Using Stellar™ Competent Cells(Section VIII of the User Manual)This transformation protocol has been optimized for transformation using Stellar Competent Cells, sold inIn-Fusion kits and separately in several formats. If you are not using Stellar Competent Cells, follow the protocol provided by the manufacturer. We strongly recommend the use of competent cells with a transformation efficiency ≥1 x 108 cfu/ug.For complete information on the handling of Stellar Competent Cells, please see the Protocol.1.Thaw Stellar Competent Cells on ice just before use. After thawing, mix gently to ensure even distribution,and then move 50 µl of competent cells to a 14-ml round-bottom tube (Falcon tube). Do not vortex.2.Add 2.5 µl of the In-Fusion cloning reaction to the competent cells.3.Place the tubes on ice for 30 min.4.Heat shock the cells for exactly 45 sec at 42°C.5.Place the tubes on ice for 1–2 min.6.Add SOC medium to bring the final volume to 500 µl. SOC medium should be warmed to 37°C before using.7.Incubate with shaking (160–225 rpm) for 1 hr at 37°C.8.Plate 1/5–1/3 of each transformation reaction into separate tubes and bring the volume to 100 µl with SOCmedium. Spread each diluted transformation reaction on a separate LB plate containing an antibioticappropriate for the cloning vector (e.g., the control vector included with the kit requires 100 µg/ml ofampicillin.)9.Centrifuge the remainder of each transformation reaction at 6,000 rpm x 5 min. Discard the supernatant andresuspend each pellet in 100 µl fresh SOC medium. Spread each sample on a separate antibiotic LB plate.Incubate all plates overnight at 37°C.10.The next day, pick individual isolated colonies from each experimental plate. Isolate plasmid DNA using astandard method of your choice (e.g., miniprep). To determine the presence of inserts, analyze the DNA byrestriction digest or PCR screening.IV. Expected Results (Section IX of the User Manual)The positive control plates typically develop several hundred white colonies when using cells with a minimum transformation efficiency of 1 x 108cfu/μg. The negative control plates should have few colonies.The number of colonies on your experimental plates will depend on the amount and purity of the PCR products and linearized vector used for the In-Fusion cloning reaction.∙The presence of a low number of colonies on both the experimental plate and positive control plate (typically,a few dozen colonies) is indicative of either low transformation efficiency or low quality DNA fragments.∙The presence of many (hundreds) of colonies on the negative control is indicative of incomplete vector linearization.If you do not obtain the expected results, use the guide in Section X of the User Manual to troubleshoot yourexperiment. To confirm that your kit is working properly, perform the control reactions detailed in Section IV.D of the User Manual.NOTE: Many troubleshooting topics are covered in our online In-Fusion Cloning FAQs and Tips.Notice to PurchaserOur products are to be used for research purposes only.

Configuration and Status RegisterWord address 13 (D in Hex) is used for both module configuration and module status. The Module Status Register has both status and diagnostic information. The bit information contained within these words is shown in Table 19A-5.Definitions for the Configuration/Module Status Register bits:Bit 0:This bit configures the module (write) or indicates the configuration state of the module (read). A “1” indicates that the module is configured. Note that until the module is configured, reading from addresses #0 through #11 (B in Hex) will produce an attention status.Bit 1:This bit (write “1”) forces the module into the error state, resulting in the error LED being lit. The read of bit “1” indicates that there is an internal module error,or the controller has forced the module into the error state.

m6A文献解读
m6A文献解读相xhog0.8842020.05.10 11:11:23字数 1,442阅读 763前几天我们一直在介绍m6A相关的数据库,正好好久没之前看过一篇关于m6A的文献。
这里就来做一下这个文献的抄读吧。
今天抄读的这篇文献是2019年来自于中山大学发表的一篇m6A 相关的文献。
imageMETTL3在结肠癌当中的基本结果为了评价m6A在大肠癌当中的作用,作者首先评价了m6A的相关基因在TCGA数据库当中的结肠癌的差异表达的情况。
同时利用自己的医院的样本来检验这些差异表达结果的情况。
同时发现METTL3在验证的结果当中存在表达差异。
image一般做组织样本分析的除了做癌和正常的分析,也会进一步的表达和各种临床信息有没有差异的。
所以作者就做了关于METTL3和各种临床信息的分析。
这种一半肯定会做很多临床数据的分析,至于结果的话,可能就是哪个有意义就上哪个了。
imageSOX2收到METTL3介导的m6A甲基化的调控在上面进行各个细胞系表达验证的时候,作者发明METTL3在SW480以及SW620之间的蛋白表达存在差异。
这一对细胞系是从单个患者的腹部转移灶和原发肿瘤中分离出的一对细胞系,两种细胞系表现出不同的转移能力可能说明METTL3和肿瘤的转移存在关系。
image对于m6A测序方面的分析,就是使用MeRIP-seq了。
所以作者做了两组不同的MeRIP-seq的分析。
一组是SW480 vs SW620。
另外一组由于METTL3在SW620当中表达高。
所以就做了SW620 VS 敲除METTL3的SW620细胞系(这个分组的SW620估计就是之前的第一组的那个吧)。
由于我们也介绍过MeRIP-seq只能说明m6A和哪个位置结合,但是并不能说明影响表达,对于相同的分组,作者也做了RNA-seq的分析。
通过最后的交叉分析,最后可以得到158个基因是是两个分组重叠出来的结果。
image进一步对这158个基因进行了富集分析,说明这158个基因主要是和干细胞分化有关系,说明METTL3介导的转移有可能是通过干细胞分析通路来形式作用的。

RNA碱基修饰以及m6A的前世今生——m6A专题
RNA碱基修饰以及m6A的前世今生| m6A专题N6-methyladenosine也叫m6A,是一种广泛存在于mRNA上的碱基修饰行为,成为近几年大热的研究方向。
但是早在50年前,人们已经在RNA中发现了多种碱基修饰现象。
除了传统的ACGU四种碱基外,Cohn等人已经在RNA上发现了全新的碱基位点修饰。
Holley等人于1965年,首次在酵母的tRNA中鉴定了包括假尿苷(pseudouridine)在内的十余种不同的RNA修饰。
当然最初这些碱基修饰大多发现于非编码RNA上如tRNA、rRNA等,后来人们发现mRNA中也存在大量的碱基修饰行为。
图1 tRNA上广泛存在大量的碱基修饰,最高比例可达近30%已知tRNA上发生碱基修饰的比例较高,会有各种各样的碱基修饰行为。
tRNA修饰有助于提高翻译效率,维持其三叶草折叠二级结构的稳定性。
人类的核糖体RNA(rRNA)上有超过200个碱基修饰位点,而剪切体RNA(spliceosomal RNA)上也有超过50个碱基修饰位点。
图2 真核生物mRNA上存在的各种碱基修饰行为,在5’和3’的UTR以及中间的coding region都有碱基发生修饰目前科学家已经在RNA中鉴定了超过100种不同类型的碱基修饰行为。
在真核生物中,5’端的Cap以及3’的ployA修饰在转录调控中起到了十分重要的作用,而mRNA 的内部修饰则用于维持mRNA的稳定性。
mRNA最常见的内部修饰包括了N6-腺苷酸甲基化(m6A)、N1-腺苷酸甲基化(m1A)、胞嘧啶羟基化(m5C)等。
对于大热的m6A,截止当前,全球的科学家已经鉴定了参与m6A的许多酶,包括去甲基化酶、甲基化酶和甲基化识别酶等(将在下期进行详细介绍)。
图3 m6A甲基化修饰和m6Am超甲基化修饰的概念我们先来了解下什么叫m6A修饰。
从图3中我们可以看到,右侧存在m6A甲基化修饰和m6Am超甲基化修饰。
重复一下N6-methyladenosine就是m6A,一共分为2个大的结构。
