FIG. 3.

Profiles of anti-SIV antibody responses of noncontroller and controller monkeys. (a) SIV proteins, prepared from detergent-treated pelleted particles, were transferred to PVDF membranes following PAGE and incubated with a 1:500 dilution of serially collected plasma samples from two noncontroller monkeys (upper) and two controller monkeys (bottom). The positions of SIV gp120 envelope glycoproteins and p27 CA are indicated. A plasma sample (diluted 1:500) collected from a chronically SIVmac239-infected monkey was used as a positive control in lane P. (b) Anti-SIV gp120 ELISA titers.
