Characterization of the GPC-mediated cell entry by GPC-pseudotyped lentiviral VLPs. (A) Expressions of P2, P18, and P18 mutant GPC proteins in the transfected 293T cells. Western blot analysis was conducted using guinea pig anti-PICV serum. (B) Detection of G1/G2 and HIV-1 p24 in the purified VLPs by western blot analysis. Intensity of each band was quantified by the Image J analysis software and normalized to that of P18.
