Thermo Scientific RevertAid First Strand cDNA Synthesis Kit is a complete system for efficient synthesis of first strand cDNA from RNA templates. The kit uses RevertAid Reverse Transcriptase (RT), a recombinant M-MuLV RT which maintains activity at 42–50°C and is suitable for synthesis of cDNA up to 13 kb. RiboLock RNase Inhibitor, supplied with the kit, effectively protects RNA templates from degradation at temperatures up to 55°C.

The RevertAid First Strand cDNA Synthesis Kit is supplied with both oligo(dT)₁₈ and random hexamer primers. The oligo(dT)₁₈ primer anneals selectively to the poly(A) tail of mRNA. Random hexamer primers do not require the presence of the poly(A) tail; they can therefore be used for transcription of the 5'-end regions of mRNA or cDNA synthesis of RNA species lacking a poly(A) tail (e.g., microRNAs). Gene-specific primers may also be used with the kit.

Radioactively- and non-radioactively-labeled nucleotides can be incorporated into first strand cDNA for use as a probe in hybridization experiments, including microarrays.

Features of the RevertAid First Strand cDNA Synthesis Kit include:
• Full-length first strand cDNA up to 13 kb
• Optimum reaction temperature 42°C
• Complete kit with all components necessary for the RT reaction already included

Applications
• First strand cDNA synthesis for RT-PCR and RT-qPCR
