What is the total RNA for cDNA synthesis?
You can use 2 ug of total RNA for cDNA synthesis which is good enough for further qPCR studies.
What does it mean to synthesize cDNA?
cDNA Synthesis describes the generation of complementary DNA (cDNA) from an RNA template by reverse transcription. 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.
Why is cDNA synthesis?
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.
How do you synthesize cDNA from RNA?
- Prepare sample. RNA serves as the template in cDNA synthesis.
- Remove genomic DNA. Trace amounts of genomic DNA (gDNA) may be co-purified with RNA.
- Select reverse transcriptase.
- Prepare reaction mix.
- Perform cDNA synthesis.
- Prepare sample.
- Remove genomic DNA.
- Select reverse transcriptase.
What is called cDNA?
Complementary DNA (cDNA) is a DNA copy of a messenger RNA (mRNA) molecule produced by reverse transcriptase, a DNA polymerase that can use either DNA or RNA as a template. From: Encyclopedia of Genetics, 2001.
Why is RNA converted to cDNA?
cDNA is a more convenient way to work with the coding sequence than mRNA because RNA is very easily degraded by omnipresent RNases. This the main reason cDNA is sequenced rather than mRNA. Likewise, investigators conducting DNA microarrays often convert the mRNA into cDNA in order to produce their probes.
Why is cDNA used?
The cDNA can be used for PCR, gene discovery, analysis or mRNA, and cloning among others.
