CD70-fiber BsAb enhance AdZ and AdR entry into LCL-1 cells. (A) LCL-1 cells, with or without CD70-fiber BsAb, were either mock infected, infected with AdZ, or infected with AdLacZ. All infections were done at an MOI of 20. After 2 days, immunoblot assays were performed on extracts from each sample, followed by staining with a MAb against BZLF1. Staining for β-actin was used to ensure equal sample loading. (B) LCLs, with or without CD70-fiber BsAb, were mock infected, infected with AdR, or infected with AdLacZ. After 2 days, immunoblot assays were performed on extracts from each sample, followed by staining with a MAb against BRLF1 or actin. NS indicates a nonspecific band.
