FIG. 1.

Virus particle release. 293T cells were transfected with wt and mutant HIV constructs. Cell lysates and pelleted virus samples were collected at 72 h posttransfection and subjected to SDS-PAGE followed by immunodetection for Gag proteins with an anti-HIV-1 CA antibody. Sample identities and bands for PrGag, CA, and the p41 processing intermediate are indicated.
