Kinetics of antibody response and estimation of end point titers of murine antisera raised during course of immunization in different formulations for V3-gp41 (A-D), gp41 (E-H), p17(I-L) and p24(M-P). HIV-1 peptides. Mice were immunized as described in Materials and Methods in different antigenic formulations. The serum antibody titers were determined by ELISA. Titers were assessed as the highest sera dilution giving an absorbance of > 0.3.
