ResumoA TaqMan fluorescent probe-based product enhanced reverse transcriptase (RT) assay is described in which the RT and polymerase chain reaction (PCR) steps are set-up in a single tube, in two compartments separated by Ampliwax (designated as single-tube fluorescent product-enhanced reverse transcriptase assay (STF-PERT)). This simplification of the two-step method resulted in increased assay reproducibility and handling efficiency while maintaining the sensitivity of the PERT assay (<10 virions). The STF-PERT assay can be used to quantitate low amounts of retrovirus in clinical and research materials and to evaluate retrovirus contamination in cell substrates and biological products in human use.
