How does cDNA synthesis work?

How does cDNA synthesis work?

The synthesis of DNA from an RNA template, via reverse transcription, results in complementary DNA (cDNA). cDNA can then serve as template in a variety of downstream applications for RNA studies such as gene expression; therefore, cDNA synthesis is the first step for many protocols in molecular biology.

What is first-strand cDNA synthesis?

The synthesis of DNA from an RNA template, via reverse transcription, produces complementary DNA (cDNA). Alternatively, the first-strand cDNA can be made double-stranded using DNA Polymerase I and DNA Ligase. These reaction products can be used for direct cloning without amplification.

How does superscript III cellsdirect cDNA synthesis kit work?

The SuperScript III CellsDirect cDNA Synthesis Kit is optimized for synthesizing first-strand cDNA directly from a mammalian cell lysate without first isolating the RNA. Lysis and reverse transcription are performed in the same tube, and the resulting first-strand cDNA is ready to use in cloning and PCR.

How is Invitrogen superscript III reverse transcriptase created?

Invitrogen SuperScript III Reverse Transcriptase is a genetically engineered MMLV reverse transcriptase (RT) that was created by introduction of several mutations for reduced RNase H activity, increased half-life, and improved thermal stability.

How big is the superscript III first strand synthesis system?

The SuperScript® III First-Strand Synthesis System for RT-PCR is optimized to synthesize first-strand cDNA from purified poly (A) + or total RNA. RNA targets from 100 bp to >12 kb can be detected with this system. The amount of starting material can vary from 1 pg–5 µg of total RNA.

How much RNA can be detected with superscript III?

RNA targets from 100 bp to >12 kb can be detected with this system. The amount of starting material can vary from 1 pg–5 µg of total RNA. SuperScript® III Reverse Transcriptase is a version of M-MLV RT that has been engineered to reduce RNase H activity and provide increased thermal stability.
