> What kind of reverse transcriptase is used in qRT-pcr is there a standard like taq dna pol is used for qPCR
M-MuLV (Monoley murine leukemia virus) reverse transcriptase
Some RT enzymes are engineered to remove the RNAseH domain so that template RNA persists for more rounds of RT.
> Is it possible to use a biologically active Telemorease Elongation Reverse Transcriptase (TERT) in the place of the Reverse Transcriptase
Perhaps it can catalyse an RT reaction in-vitro. But commercial enzymes need to be efficient and I think using TERT won't be that advantageous.
