摘要:
Measles virus envelope pseudotyped LV (MV-LV) can achieve high B cell trans-duction rates (up to 50%), but suffers from low titers. To overcome current limi-tations, we developed an optimized MV-LV production protocol that achieved consistent B cell transduction efficiency up to 75%. We detail this protocol along with analytical assays to assess the results of MV-LV mediated B cell transduction, including flow cytometry for B cell phenotypic characterization and measurement of transduction efficiency, and ddPCR for VCN analysis.
