DuraScribe?T7轉(zhuǎn)錄試劑盒可生成抗RNase A降解的DuraScript?RNA。 這是通過在DuraScribe體外轉(zhuǎn)錄反應(yīng)中用2'-氟-dCTP(2'-F-dCTP)和2'-氟-dUTP(2'-F-dUTP)完全替換經(jīng)典CTP和UTP來實(shí)現(xiàn)的。 該試劑盒采用DuraScribe T7 RNA聚合酶,一種突變型T7 RNA聚合酶,可有效地將2'-F-dCTP和2'-F-dUTP,ATP和GTP整合到RNA中。 DuraScribe T7 RNA聚合酶使用與標(biāo)準(zhǔn)T7 RNA聚合酶相同的轉(zhuǎn)錄啟動子序列。
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.
優(yōu)點(diǎn):
穩(wěn)定:由該試劑盒生產(chǎn)的DuraScript?RNA完全耐受RNase A降解;
高產(chǎn)量:根據(jù)轉(zhuǎn)錄本的大小,至少產(chǎn)生110~307 pmol的DuraScript?RNA;
模板靈活:使用標(biāo)準(zhǔn)T7啟動子,接受各種模板DNA,包括線性化載體,PCR產(chǎn)物,cDNA和dsDNA寡核苷酸;
多用途兼容:合成具有RNase A抗性的長或短轉(zhuǎn)錄本,以便用于SELEX篩選核酸適配體或RNA干擾。
