Specific cytolytic activity against HIV-1NL4-3 gp120 in mice immunized with SV(gp120) and assayed one month after final injection. BALB/cJ mice were immunized twice with SV(gp120) IP at monthly intervals. Splenocytes were harvested one month after final inoculation. Unselected effector cells were added to ⁵¹Cr-labelled target cells and specific lysis of gp120-expressing cells was calculated as described in Methods, ± S.E.M. Results shown here represent ≥ 3 independent determinations per data set.
