Figure Legend: HEK 293 cells were transfected with 5, 10, 30 or 50 nM of Silencer FAM Labeled GAPDH siRNA with either GeneSilencer (Genlantis) or siPORT NeoFX (Ambion) siRNA transfection reagents according to the manufacturer"s recommended protocols. Cells were incubated for 48 hours then fixed, permeablized, and incubated with AlexaFluor 555 phalloidin (Invitrogen), which stains cellular actin red. Cells were then mounted on slides and stained with DAPI (Invitrogen), which stains the cell nuclei blue. Transfected cells were visualized by fluorescence microscopy using identical exposure times for FITC, TRITC, and DAPI. The transfected GAPDH siRNA is localized in the cell cytosol and can be seen as green fluorescent specks or dots.

How to Design siRNA (Small Interfering RNA)
The sequence of the siRNA can be selected as follows:
The sequence selection process has no other constraints. It is important to note that structure within thetargeted mRNA appears to have minimal effect on the availability of the mRNA target and efficacy of thesiRNA silencing approach. To-date, successful silencing has been achieved using the above method toselect the target sequence, although the method is essentially random with respect to accounting for mRNAstructure.Although siRNA silencing appears to be extremely effective by selecting a single target in the mRNA, itmay be desirable to design and employ two independent siRNA duplexes to control for specificity of thesilencing effect. This recommendation is only for specificity for it is yet unknown if the targeting of a geneby two different siRNA duplexes would be more effective than using a single siRNA duplex. It is believedthat the rate-limiting component of the siRNA effect is the availability of cellular nuclease components andnot mRNA target availability. Therefore, doubling the number of siRNA duplexes is not expected to doublethe rate or efficiency of silencing.If the selected siRNA duplex(es) do not function for silencing, the following steps are recommended. First,a search is conducted for sequencing errors in the gene and possible polymorphisms. Initial studies on thespecificity of target recognition by siRNA duplexes indicates that a single point mutation located in thepaired region of an siRNA duplex is sufficient to abolish target mRNA degradation. Second, a reexaminationis performed to confirm whether the cell line is from the expected species. Third, a secondand/or third target are selected and the corresponding siRNA duplexes prepared.

逆转录酶的具体作用是什么 业百科123

反转录和逆转录有什么区别? 123
生曰快樂_02482021-08-15
两者是同一生理过程的不同提法，没有本质的区别，都是遗传信息流动的方向是从RNA到DNA。但在一些考题中，它们又有所区别的。反转录是人工条件下，借用逆转录酶，根据逆转录原理，实现用细胞生物mRNA为模板，合成目的基因的过程。目的基因的获得方法中有反转录法，而中心法则的补充时则用逆转录法。就像下面的一道考题，答案就是B。已获得了某种蛋白质的mRNA,通过利用这个mRNA分子获得目的基因,在下列获得目的基因的方法中,哪一种最可取（ ） A、超速离心法 B、反转录法 C、逆转录法 D、鸟枪法cDNA为具有与某RNA链呈互补的碱基序列的单链DNA，即complementary DNA之缩写，或此DNA链与具有与之互补的碱基序列的DNA链所形成的DNA双链。
在基因工程里什么时候是反转录什么时候是逆转录123
Saydaai2021-07-22
人工合成基因的方法主要有两条途径：一是以目的基因转录成的mRNA为模板，逆转录成互补的单链DNA，然后在酶的作用下合成双链DNA，从而获得所需要的基因；二是根据已知的蛋白质的氨基酸序列，推测出相应的 mRNA序列，然后按碱基互补配对原则，推测出它的结构基因的核苷酸序列，再通过化学的方法，以单核苷酸为原料合成目的基因。
逆转录（reverse transcription）是以RNA为模板合成DNA的过程，即RNA指导下的DNA合成。是RNA病毒的复制形式，需逆转录酶的催化。艾滋病病毒(HIV)就是一种典型的逆转录病毒。
逆转录与反转录严格意义上来说没有什么区别，但是逆转录是RNA类病毒自主行为，在整合到宿主细胞内以RNA为模板形成DNA的过程；反转录是进行基因工程过程中，人为地提取出所需要的目的基因的信使RNA，并以之为模板人工合成DNA的过程。二者虽同为RNA→DNA的过程，但地点不同，相对性的来说，逆转录在体内，反转录在体外。

没有序列识别的功能，他就是简单的催化相邻DNA链的5-P末端和3'-OH末端以磷酸二酯键结合的反应，需ATP作辅酶。 不仅可以催化粘性末端之间或平滑末端之间的DNA的连接，也催化DNA与RNA之间以及少数RNA之间的连接。
反转录酶（Reversetranscripatase）是以RNA为模板指导三磷酸脱氧核苷酸合成互补DNA（cDNA）的酶。哺乳类C型病毒的反转录酶和鼠类B型病毒的反转录酶都是一条多肽链。鸟类RNA病毒的反转录酶则由两上亚基结构。真核生物中也都分离出具有不同结构的反转录酶。

为什么说端粒酶是反转录酶123
你大爷JmIp2018-03-17
为什么说端粒酶是反转录酶
只要是细胞，就得走向衰老，现代研究表明，细胞的衰老和端粒的变短有关系。端粒就是DNA，随着细胞分裂次数的增多，端粒在不断变短，端粒酶就是组织端粒变短的。然而正常细胞中，端粒酶的活性受抑制，端粒酶是怎么染端粒变长的呢？实际上端粒酶是由RNA组成的，可以根据碱基互补配对逆转形成DNA，使得变短的端粒变长。所以说端粒酶可以逆转录形成端粒，使端粒不减短！

RNA聚合酶Ⅰ存在于核仁中，转录rRNA顺序。RNA聚合酶Ⅱ存在于核质中，转录大多数基因，需要“TATA”框。RNA聚合酶Ⅲ存在于核质中，转录很少 RNA聚合酶几种基因如tRNA基因如5SrRNA基因。有些重复顺序如Alu顺序可能也由这种酶转录。

RT-nPCR实际叫做反转录-巢式PCR，反转录PCR就是把RNA提取后反转录成cDNA，并以其为模板进行的PCR反应，通常用于检测某种RNA是否被表达，或者比较其相对表达水平巢式PCR（nested PCR），是指利用两套PCR引物（巢式引物）对进行两轮PCR扩增反应。在第一轮扩增中，外引物用以产生扩增产物，此产物在在内引物的存在下进行第二轮扩增。由于巢式PCR反应有两次PCR扩增，从而降低了扩增多个靶位点的可能性（因为与两套引物都互补的引物很少）增加了检测的敏感性；又有两对PCR引物与检测模板的配对，增加了检测的可靠性。所以反转录-巢式PCR就是以cDNA为模板进行的巢式PCR，它和简单的反转录PCR一样是用于检测某种RNA是否被表达，或者比较其相对表达水平，但是特异性更高，可靠性更强。
反转录酶的注意事项123
灰太狼咳卫2352021-08-01
反转录酶
在进行RT反应之前，应考虑以下几个方面：
1、RNA
成功的cDNA合成来自高质量的RNA，高质量的RNA至少应保证全长并且不含逆转录酶的抑制剂，如EDTA或SDS。在提取RNA的过程中，要特别防止RNase的污染，同时在逆转录反应中经常加入RNase抑制剂以增加cDNA合成的长度和产量。RNase抑制剂要在第一链cDNA合成反应中，在缓冲液和还原剂（如DTT）存在的条件下加入，因为cDNA合成前的过程会使抑制剂变性，从而释放结合的可以降解RNA的RNase。蛋白RNase抑制剂仅防止RNaseA，B，C对RNA的降解，并不能防止皮肤上的RNase，因此尽管使用了这些抑制剂，也要小心不要从手指上引入RNase，实验过程中经常更换新手套。
2、引物的选择
OligodT
选择OligodT时，要求RNA必须有PolyA，所以真核生物的mRNA都适用。适合长链甚至全长mRNA的RT，所以对RNA样品的质量要求较高，最好不要有明显的DNA污染、RNA降解和RNA断裂。假如想探索新的mRNA进行RT反应，建议推荐使用OligodT引物。使用OligodT引物要比随机引物和特异性引物的稳定性要好。
随机引物
适合各种RNA的RT，尤其适合模板丰度很低的情况（比如某个gene表达量很低）。选择随机引物时，第一链cDNA合成反应中就是以所有的RNA为模板，然后进行PCR反应时设计引物进行特异性扩增。同时要注意随机引物的量和总RNA量之间的关系，一般建议每5μg总RNA的随机引物的用量为50ng，如果每5μg总RNA的随机引物的用量超过250ng，可能会导致小片段产物（<500bp）的增加和长片断、全长产物产物的降低。
特异性引物
特异性引物只能用你设计引物时的下游引物做RT，引物设计质量影响RT的结果，而且不同引物退火温度本来就不相同，所以按照说明书按照一个温度做不是最佳选择，一般不推荐。向左转|向右转
