FIG. 8.

Plasma variants present in monkeys infected in a serial IVAG and serial IV passage. After inoculation with SIVmac251, plasma collected at week 2 p.i. was inoculated into monkeys IVAG or IV. Plasma donors 1 and 2 for the IVAG passages (D1 and D2) and donors 3 and 4 for the IV passages (D3 and D4) are indicated. Lanes 1 and 8, SIVmac251-8/95 virus stock; lanes 2 and 3, variants at weeks 1 and week 2 (wk. 1 and wk. 2) p.i. from monkey 21743 inoculated IVAG with SIVmac251; lanes 4 to 7, variants at weeks 1 and 2 p.i. in monkeys inoculated IVAG with plasma from 21743; lanes 9 and 10, variants at weeks 1 and 2 p.i. from a monkey (22673) inoculated IV with SIVmac251-8/95; lanes 11 and 12, variants at weeks 1 and 2 p.i. in a monkey inoculated IV with plasma from 22673; lanes 13 and 14, variants at weeks 1 and 2 p.i. in a monkey inoculated IV with plasma from 22766.
