FIG. 3.

Comparison of in vitro-synthesized p12 domain deletion mutant Gag species by sucrose gradient analysis. The experiment was performed and lane designations and molecular size standards are as described for Fig. 2. Lanes 8 to 10 containing material indicative of immature capsids are of a density of ∼1.19 to 1.21 g/ml. M100A, Δ8-58/M100A, and Δ1-83/M100A indicate analyses of translation reactions programmed with the corresponding gag genes.
