cDNA Synthesis Kits on ZAGENO

cDNA synthesis is the process of synthesizing DNA from messenger RNAs (mRNAs). The resultant complementary DNA (cDNA) constitutes the starting material for molecular cloning, hybridization probes and the creation of clone libraries, but is also commonly used for transcriptome analysis in qPCR or microarray experiments. It is a necessary initial step for PCR of an RNA sample.

Synthesizing cDNA

For research purposes, cDNA is typically synthesized from purified mRNA using an in-vitro reverse transcriptase reaction. There are plenty of kits available on the market, called either cDNA synthesis or reverse transcription kits, supplying all the reagents needed to make your cDNA synthesis easy and cost-effective. However, there are a few factors to consider when choosing the right product.
The starting templates are generally:

Typically, cDNA synthesis kits synthesize either first-strand or double-stranded cDNA:

  • Double-stranded synthesis is required for cloning applications

It is also essential to be aware of the sensitivity of your kit, particularly for quantitative applications. Kits able to amplify minute differences in mRNA expression can be the key to successful experiments. Similarly, thermostable enzymes allow for the use of higher temperatures that can disentangle complex RNA secondary structures, resulting in a more representative amplification and more precise quantification.
Last but not least, the kit should fit your experimental workflow. In this regards, sample processing speed might be worth considering, alongside with suitability for automatic processing or buffer compatibility with your downstream applications.

Compare cDNA Synthesis Products!

To assist you in choosing the correct purification product for your research, ZAGENO has developed an easy-to-use comparison feature, aligning the important attributes for each kit in a simple table.

Click on the comparison below for a clearer view!

This example highlights how every kit has positive and negative aspects, and that only side-by-side comparison can allow you to correctly judge which is the right kit for you.

For instance, this comparison shows:

  • that the GE Life Sciences First-Strand cDNA Synthesis Kit can use the largest amount of sample
  • that the Bioline Tetro cDNA Synthesis Kit is the cheapest kit
  • that the Roche Life Science Transcriptor First Strand cDNA Synthesis Kit can also use viral RNA as the template

The ZAGENO comparison engine does not show the best kit, but instead helps you, the researcher, choose the most sutiable kit for your experiment.
