Production of monoclonal and polyclonal antibodies against prostate-specific antigen, a prostate cancer serum marker.
The aim of this study was to produce monoclonal and polyclonal antibodies against prostate-specific antigen (PSA), a prostate cancer serum marker. Hyperimmune ICR mice produced polyclonal antibodies (PoAbs) after injection with 0.5 mL of pristane, and were injected with NS-1 myeloma cells 2 weeks later. Hyperimmune Balb/c mice were used for the production of monoclonal antibodies (MAbs). Mice were immunized four times and given a final boost, and their spleen cells were collected and fused with NS-1 myeloma cells under the presence of PEG 1500. The fused cells were then selected in the HAT-RPMIX medium. Anti-PSA antibody-secreting hybridoma cell lines with high titer were cloned by enzyme-linked immunosorbent assay (ELISA) and then subcloned by limiting dilution in 15% fetal bovine serum (FBS) HT-RPMIX medium. Twelve murine hybridoma producing anti-PSA MAbs were obtained and designated C3m1G11, B3m1E5, C3m1E8, C3m1C5, C3m2F4, C3m1F8, C3m2B3, C3m2E6, B3m2B11, B3m2F2, C3m2C7, and C3m2D9. Isotypes of these MAbs were identified as IgG2a heavy chain and kappa light chain. Hitrap Protein A column was used for the purification of polyclonal and monoclonal antibodies. The purity analysis of MAb was performed by capillary electrophoresis.
