WebSep 1, 1975 · A rapid focus-induction assay has been developed for certain replicating (r+) but nontransforming (t−) mammalian type C viruses including xenotropic murine leukemia virus (X-MuLV), feline leukemia virus C (FeLV-C), and feline-primate viruses RD … WebComparative studies demonstrated that the PG4 S+L- retrovirus infectivity test routinely yields higher titres than the mink cell test for xenotropic, amphotrophic and MCF murine retroviruses. A validation study for the PG4 S+L- assay demonstrated very good linearity (r2 of 0.95 to 0.99), reproducibility within a study (+/-0.35 log10 units), and ...

WebJul 8, 2015 · On the other hand, S+L- assay using feline S+L- cells, termed QN10S, could not detect porcine endogenous retrovirus (PERV) subgroups A/B. Further, S+L- mink cells could not detect feline leukemia virus subgroups B in addition to PERV-A/B. These data indicate that LMR assay is better suited to detect wider range of gammaretroviruses.
