Power cDNA Synthesis Kit is used to synthesize first-strand cDNA from total RNA or mRNA template. It contains all components necessary for cDNA synthesis such as AMV reverse transcriptase and RNase inhibitor etc. The central dogma (expression from DNA to protein) is very important for the understanding of life phenomena. In the past, when these expression studies were carried out on proteins. However in recent years, research on mRNAs, transcription factors for protein expression, has became ore active. This is because analysis of expression genes is more accurate and easier than protein analysis.
Therefore RNA research is preferred along with advantages of cost saving such as reagents and time. What made it possible is reverse transcriptase from retroviruses, and finally the RNA-dependent DNA polymerase can make complementary DNA to RNA. These reverse transcriptase enzymes have ribonuclease H activity, which only degrades RNA in the RNA-cDNA hybrid state after the reverse transcription termination. As a result, cDNA remains only.
In reverse transcription reactions, the purity and amount of the RNA template determines the efficiency of the reaction. Therefore, should be careful to avoid the incorporation of RNase into RNA samples, and make sure not to be mixed by proteins, poly-anions (eg, heparin), salts, EDTA, ethanol, phenol and other solvents. The Power cDNA Synthesis Kit uses the high-efficiency AMV reverse transcriptase, it is efficient for obtaining full-length cDNA. And it is useful to use for the expression of low copy gene because it was developed with optimal first cDNA synthesis conditions. In addition, it is very easy to synthesize the best cDNA and ensures optimal results when performing PCR.

Application for various samples
After extraction of total RNA from virus and cell using Viral Gene-spinTM Viral DNA/RNA Extractio Kit (Cat. No. 17151) and easy-BLUETM Total RNA Extraction Kit (Cat. No. 17061), first strand cDNA was synthesized by Power cDNA Synthesis Kit then PCR performed. In result, it was varified that RT reaction is possible with templates from 20bp to 3Kb.
