反轉(zhuǎn)錄酶III 逆轉(zhuǎn)錄酶三 invitrogen原裝 SuperScript III Reverse Transcriptase
貨號(hào)18080-044
與SuperScriptII逆轉(zhuǎn)錄酶一樣,SuperScriptIII的RNase H 活性較低,能獲得更高產(chǎn)量的全長(zhǎng)Cdna。另外,它還有著其它的逆轉(zhuǎn)錄酶所無(wú)法提供的熱穩(wěn)定性;經(jīng)過(guò)基因工程改造的SuperScriptIII具有更高的熱穩(wěn)定性,其半衰期在50度時(shí)達(dá)到令人難以置信的220分鐘,這個(gè)特性也提高SuperScriptIII轉(zhuǎn)錄具有二級(jí)結(jié)構(gòu)模板RNA的能力。
保證,原產(chǎn)批號(hào)可查,大量現(xiàn)貨,歡迎選購(gòu)。

SuperScript III Reverse Transcriptase (RT) is a proprietary mutant of SuperScript II RT that is active at 50°C and has a half-life of 220 minutes, providing increased specificity with Gene-Specific Primers (GSPs) and the highest cDNA yield of all RTs. It is ideal for RT-PCR of a specific gene or generating cDNA from total or poly (A)+RNA sample. Like SuperScript II, it synthesizes a complementary DNA strand from single-stranded RNA, DNA, or an RNA:DNA hybrid. SuperScript III RT is genetically engineered by the introduction of point mutations that increase half-life, reduce RNase activity, and increase thermal stability.
Thermostability– Half life of 220 minutes at 50°C
Yield– Reduced RNase H activity for more full-length cDNA
Specificity– Full activity at 50°C for increased specificity with Gene Specific Primers
Applications– Array labeling, cDNA libraries, RT-PCR, primer extension, and 3 and 5 RACE
