General description

eAMV Reverse Transcriptase is an enhanced form of Avian Myeloblastosis Virus (AMV) RT that synthesizes a DNA strand complementary to RNA, DNA, or an RNA:DNA hybrid. This exceptionally robust AMV RT has greater thermostability than standard AMV or Moloney murine leukemia virus(M-MLV) reverse transcriptase. eAMV RT is an ideal enzyme for producing high-quality full-length cDNA from total RNA or poly(A)+ RNA and is also efficient at transcribing long targets.


Enhanced Avian Reverse Transcriptase (eAMV RT) is used to transcribe RNA into DNA, and facilitates efficient mRNA template driven sysnthesis of cDNAs. This is due to the abillity of this enhanced AMV-RT to transcribe large mRNA templates, to transcribe through difficult secondary structures, and to detect low abundance mRNAs by RT-PCR.
Enhanced Avian Reverse Transcriptase [eAMV RT] has been used for reverse transcription of total RNA to synthesize cDNA during quantitative reverse transcription PCR (RT-qPCR) analysis.

Biochem/physiol Actions

Reverse transcriptase catalyzes RNA template incorporation of dNTPs into complimantary DNA through phosphodiester bond formation.

Features and Benefits

  • Greater sensitivity for low abundance mRNA
  • Unsurpassed transcription through difficult secondary structures at elevated temperatures (up to 65°C)
  • Efficient generation of full-length cDNA, up to 14.1 kb
  • Produces first strand cDNA ready for PCR amplification


Provided with a vial of 10× reaction buffer.

Unit Definition

One unit incorporates one nanomole of TMP into TCA precipitable material in 10 min using polyadenylic acid as template and oligo(dT)12-18 as a primer.

Reverse Transcription

One approach to the analysis of gene expression is to measure the concentration of mRNA of a gene. There are several challenges to such analyses, such as the differences in half life between different transcripts, the temporal patterns of transcription and the lack of correlation between mRNA and protein.

RT-qPCR – Quantitative Reverse Transcription PCR

RT-qPCR, or quantitative reverse transcription PCR, combines the effects of reverse transcription and quantitative PCR or real-time PCR to amplify and detect specific targets. RT-qPCR has a variety of applications including quantifying gene expression levels, validating RNA interference (RNAi), and detecting pathogens such as viruses.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
