dNTP concentration for reverse transcription from RNA to cDNA

Degree of RNA intact in the reaction is very important for high quality cDNA synthesis and it is crucial to keep reagents from contamination such as RNase.

When synthesizing a protein, DNA is transcribed into mRNA which is then translated into a protein. One difference between eukaryotic and prokaryotic genes is that eukaryotic genes often contain introns which are not coding sequences, in contrast with exons, which are DNA coding sequences. During transcription, intronic RNA is excised from the RNA primary transcript and the remaining pieces of the RNA primary transcript are spliced back together resulting in processed mRNA. The mRNA code is then translated into an amino acid chain that comprises the newly made protein.

Using reverse transcriptase polymerases, DNA can be synthesised from mRNA and total RNA. Thus it is a 'complementary' copy of the mRNA, and is thus called complementary DNA (cDNA). cDNA forms the substrate for the majority of qPCR gene expression experiments.

cDNA Synthesis (Lusis Lab, UCLA) To convert RNA into cDNA

Once mRNA is converted to cDNA, the cDNA can be used for RT-PCR, as probe for expression analysis and for cloning of the mRNA sequence.

Protocol includes: 1st Strand cDNA SynthesisDetermine the efficiency of first strand cDNA synthesisSecond Strand cDNA SynthesisCleave 5' Overhanging EndsMethylate to Protect EcoRI Sites in cDNALigate to LinkersLigate cDNA to Vector

This protocol has several roots. It is based on a protocol to create cDNA for microarrays and adapted to be used for lower amounts. It works very reliable and it is my preferred way of cDNA synthesis.

RNA/Reverse Transcription (RT) & cDNA Synthesis …

The synthesis of DNA from an RNA template, via reverse transcription, produces complementary DNA (cDNA). Reverse transcriptases (RTs) use an RNA template and a short primer complementary to the 3' end of the RNA to direct the synthesis of the first strand cDNA, which can be used directly as a template for the Polymerase Chain Reaction (PCR). This combination of reverse transcription and PCR (RT-PCR) allows the detection of low abundance RNAs in a sample, and production of the corresponding cDNA, thereby facilitating the cloning of low copy genes. 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. In this case, RNase H activity, from either the RT or supplied exogenously, is required.

Many RTs are available from commercial suppliers. and Moloney Murine Leukemia Virus (M-MuLV, MMLV) Reverse Transcriptase are RTs that are commonly used in molecular biology workflows. lacks 3´ → 5´ exonuclease activity. is a recombinant M-MuLV reverse transcriptase with reduced RNase H activity and increased thermostability. It can be used to synthesize first strand cDNA at higher temperatures than the wild-type M-MuLV. The enzyme is active up to 50°C, providing higher specificity, higher yield of cDNA and more full-length cDNA product, up to 12 kb in length.

Solis BioDyne - dNTP Mix - (dATP, dCTP, dGTP and dTTP)

PrimeScript Reverse Transcriptase has exceptionally strong strand displacement activity and enables efficient preparation of cDNA up to 12 kb in length. It is robust, versatile and well-suited for applications requiring full-length cDNA such as preparation of cDNA libraries and other techniques involving first strand cDNA synthesis (RT-PCR, preparation of cDNA probes, real-time quantitative RT-PCR). PrimeScript RTase can be used for performing a reverse transcription reaction with any RNA template including GC-rich templates and RNAs with high levels of secondary structure. This enzyme is a modified, recombinant MMLV (Moloney Murine Leukemia Virus) reverse transcriptase and is verified to be RNase H Minus. Because of the excellent extension capability of PrimeScript Reverse Transcriptase, preparation of cDNA can be performed at a lower temperature (42°C), decreasing the risk of RNA degradation that can occur during conventional reactions performed at higher temperatures.
