Measles virus envelope pseudotyped LV (MV-LV) can achieve high B cell transduction rates (up to 50%), but suffers from low titers. To overcome current limitations, 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.
麻疹病毒包膜假型慢病毒 (MV-LV) 可实现高 B 细胞转导率(高达 50%),但其滴度较低。为了克服当前的限制,我们开发了一种优化的 MV-LV 生产方案,可实现高达 75%的一致 B 细胞转导效率。我们详细介绍了该方案以及分析检测方法,以评估 MV-LV 介导的 B 细胞转导的结果,包括用于 B 细胞表型特征分析和转导效率测量的流式细胞术,以及用于 VCN 分析的 ddPCR。
