FIG 8.
Early mutant infectivity, autologous neutralization, ERcold, and ERsCD4. (A and C) Viruses pseudotyped with d70A or d70B Env mutants were evaluated for infectivity, relative to the values observed for wild-type d70A or d70B Envs, respectively. (B and D) Sensitivity of the pseudotyped viruses to neutralization by autologous plasma from days 0 to 70 is shown. (E and F) d70B mutants were also tested for cold sensitivity (E) and sCD4 reactivity (F). All experiments were performed as described in the Fig. 1 legend. Standard errors of the means are indicated by error bars.
