FIG. 3.
Gag processing in HIVNL4-3 with or without an insert. The lysates of COS-7 cells producing HIVNL4-3 or HIV clones containing an insert and the virion lysates were examined for the Gag processing. The samples were prepared 48 h after transfection and subjected to Western blotting with anti-p24 antiserum and anti-p6 monoclonal antibody. The positions corresponding to the sizes of the fully cleaved mature proteins (p24 and p6) and the immature proteins (p55, p41, p37, and p15) are indicated by arrows.
