FIG. 6.
Serum antibody titers to SIVmac in juvenile macaques. Antibodies to SIV were assessed in longitudinal samples from experimentally inoculated macaques, using an HIV-1/HIV-2 peptide ELISA. (A) Antibody titers in juvenile macaques inoculated with ICD-TM mutants SIVmac-M1 (black symbols) or SIVmac-M4 (white symbols); (B) titers in juvenile macaques inoculated with SIVmac239Nef+ (black symbols) or SIVmac239Δ152Nef (white symbols).
