Figure 4From: A murine leukemia virus with Cre-LoxP excisible coding sequences allowing superinfection, transgene delivery, and generation of host genomic deletionsFlow cytometry analysis of GC4 cells infected by virus-producing NIH/3T3 cells in a mixed culture. GFP-Cre, EYFP, and surface envelope (Env) expression were measured. The GC4 populations were GFP-Cre+ and virus producing NIH/3T3 were GFP-Cre-. Infection by (a) Akv-Y and (b) Akv-2XY was monitored over 16 days. Subclones were isolated from boxed regions A-G by single-cell sorting.Back to article page
