FIG. 7.
INA inactivation does not affect the specific recognition of isolated viral proteins by antibodies. The indicated viral proteins from INA-treated SIV were analyzed by Western blot under reducing (R) and nonreducing (NR) conditions. Lanes: a nontreated virus; b, 1% DMSO; c, 200 μM INA; d, 20 μM INA; e, 2 μM INA; f, 200 μM INA (not photoactivated).
