Percent inhibition of Tat-transactivation after depleting anti-Tat antibodies and IgG fractions of the plasma.

All sera were diluted at 1:50 for Tat-neutralization assay. The ELISA OD values and inhibition of Tat-transactivation (inhibition (%)) are shown. “No.” represents the number of each plasma sample. a % inhibition of Tat-transactivation after depleting non-specific Tat antibodies with coated pPEPTIDE2 by ELISA. b % inhibition of Tat-transactivation after depleting Tat antibodies with coated Tat by ELISA. c % inhibition of Tat-transactivation after depleting IgG fractions with coated protein G by ELISA.
