There are a lot of choices when it comes to reverse transcriptases. Choosing the correct one for your cDNA synthesis and RT-PCR project is important. Here are a few questions that will lead you to right RT for your application:
- Are you working with a template that has high secondary structure? You may want to try Avian Myeloblastosis Virus Reverse Transcriptase (AMV RT). AMV RT is an RNA-directed DNA polymerase that catalyzes the polymerization of DNA using template DNA, RNA or RNA:DNA hybrids. AMV RT is the preferred reverse transcriptase for templates with high secondary structure due to its stability at higher reaction temperatures (37–58°C).
- Are you doing routine RT-PCR and are looking for an economical RT? Moloney Murine Leukemia Virus Reverse Transcriptase, RNase H Minus (M-MLV RT [H–]), Point Mutant, is an RNA-dependent DNA polymerase that can be used in cDNA synthesis and RT-PCR and performs very well with longer transcripts.
- Are you going to be performing RT-qPCR, working with rare or very long transcripts, or possibly working with RNA that may contain contaminating PCR inhibitors? If the answer is yes to any of those questions, GoScript™ Reverse Transcriptase is your answer. GoScript™ RT uses M-MLV and state-of-the-art buffer technology designed for qPCR to deliver robust, reliable cDNA synthesis of a full range of rare and abundant transcripts, even in the presence of inhibitors that may have been carried over from purification.
