Capsid protein processing products. The indicated virus samples were electrophoresed in parallel on conventional SDS-10% PAGE and SDS-16% PAGE Schagger gels. After electrophoresis, CA fragments were detected by immunoblotting with an anti-HIV-1-CA antibody which recognizes the HIV-1 CTD. Approximate fragment sizes in kilodaltons are indicated and were estimated by comparison with migration distances of known standards, assuming a linear relationship between migration and log molecular mass.
