RT-PCR combines two powerful and versatile techniques, reverse transcription and the polymerase chain reaction to generate and amplify cDNA from total RNA or mRNA transcripts. The method is often used to study gene expression at both the RNA and protein levels.The ideal RT-PCR requires a sensitive reverse transcription and a high fidelity amplification. The reverse transcriptase should be able to detect very low abundance transcripts and/or transcripts containing difficult secondary structure. Sigma’s enhanced Avian (eAMV™) Reverse Transcriptase displays all of these characteristics. It is the ideal RT for detecting low abundance messages that may be missed by other reverse transcriptases and it is the best enzyme we have found for transcribing through difficult secondary structure. It is also more tolerant to elevated temperatures than standard AMV, M-MLV, M-MLV RNase H– or AMV RNase H reduced.
