1. A method of performing RT-PCR of a nucleic acid sample comprising:
- mixing a composition comprising;
at least one active reverse transcriptase;
at least one active DNA polymerase; and
a combination of PCR inhibitor blocking agents consisting essentially of 0.2% w/v-0.8% w/v fish gelatin and 500 ng/μ
l to 6000 ng/μ
l BSA configured to increase tolerance to one or more PCR inhibitors when present in the nucleic acid sample, with;
a) a nucleic acid sample;
b) one or more labeled probes;
c) one or more primers; and
performing a RT-PCR on the nucleic acid sample.
