【产品推荐】DuraScribe T7 Transcription Kit/核酸酶耐受体外转录试剂盒

发表时间:2024-12-02

DuraScribe®T7转录试剂盒可生成抗RNase A降解的DuraScript®RNA。这是通过在DuraScribe体外转录反应中用2'-氟-dCTP(2'-F-dCTP)和2'-氟-dUTP(2'-F-dUTP)完全替换经典CTP和UTP来实现的。该试剂盒采用uraScribe T7 RNA聚合酶,一种突变型T7 RNA聚合酶,可有效地将2'-F-dCTP和2'-F-dUTP,ATP和GTP整合到RNA中。DuraScribe T7 RNA聚合酶使用与标准T7 RNA聚合酶相同的转录启动子序列。

The DuraScribe® T7 Transcription Kit produces DuraScript® RNA that is resistant to RNase A degradation. This is accomplished by completely replacing the canonical CTP and UTP with 2′-Fluorine-dCTP (2′-F-dCTP) and 2′-Fluorine-dUTP (2′-F-dUTP) in the DuraScribe in vitro transcription reaction. The kit features DuraScribe T7 RNA Polymerase, a mutant T7 RNA Polymerase, that efficiently incorporates 2′-F-dCTP and 2′-F-dUTP, ATP and GTP into RNA. DuraScribe T7 RNA Polymerase utilizes the same transcription promoter sequences as standard T7 RNA Polymerase.


优点:

稳定:由该试剂盒生产的DuraScript®RNA完全耐受RNase A降解;

高产量:根据转录本的大小,至少产生110~307 pmol的DuraScript®RNA;

模板灵活:使用标准T7启动子,接受各种模板DNA,包括线性化载体,PCR产物,cDNA和dsDNA寡核苷酸;

多用途兼容:合成具有RNase A抗性的长或短转录本,以便用于SELEX筛选核酸适配体或RNA干扰。
