WebDec 1, 2016 · The approach is simpler than antibody-based labeling and sorting of cells because designing PCR TaqMan assays for specific detection of sequences is much easier than generating high affinity antibodies with which to label and sort single virus particles by flow cytometry. Moreover, the implementation of TaqMan PCR allows multiplexing to ... WebApr 2, 2024 · Consequently, this cell line is commonly used to determine the functional titer of lentivirus vector stocks produced with this envelope. For lentivirus vectors encoding fluorescent proteins under the control of promoters functional in these cells, titration can be performed using the limiting dilution method or a flow cytometry-based method.
