Viruses were produced by transfection into 293T cells, virions were chemically inactivated with AT-2 and pelleted from the clarified supernatants. (A) SU (gp120) and Gag (p55, p41 and p24) proteins were detected by Western blotting using 447-52D and anti-p24 monoclonal antibodies. (B) Ratios of SU to Gag (p55+p41+p24) were calculated by using phosphorimaging analysis. Virion producer cells were lysed as indicated in the Materials and Methods section. C) SU and β-actin proteins were detected by Western blotting using 447-42D and anti-β-actin monoclonal antibodies. D) Ratios of SU to β-actin were calculated by phosphorimagiing analysis. Data for LR1-C1 are presented relative to the ratio found for AC10 _29 virions.</p
