? 2021 Elsevier B.V.Murine leukemia virus (MLV) and murine stem cell virus (MSCV) and derived retroviral vectors are widely used to study retrovirus biology and as tools for gene delivery. The method described here represents a quantitative real time PCR (qPCR) with hydrolysis probe that can be applied within classical qPCR as well as in digital droplet PCR (ddPCR). The method targets a 60 bp long fragment located within the U5 region of the MLV/MSCV genome sequence. For the here described method a LOD95% of 25 copies per PCR reaction (DNA) and 80 copies per PCR reaction (RNA) was determined, and PCR efficiencies of 92.5 % and 98.5 %, respectively, were observed. This method enables the fast and simple titration of viral genomic RNA present in retroviral vector stocks for accurate and consistent transduction experiments. Furthermore, it enables the detection of proviral and transfer plasmid derived DNA sequences and can be modified to differentiate between retroviral RNA and DNA.
