MHC Class I restriction assay. MHC class I restriction assay was performed by a cytotoxic assay of testing SV95-specific CTL lines against SV95–1 peptide-pulsed T2 cells with the addition of blocking antibody against MHC class I molecule (anti-HLA-A2, BB7.2), or MHC class II molecule (anti-MHC class II, IVA 12). SV95–6 specific CTL clone was a representative among the SV95 CTL lines. The cytotoxicity of SV95–6 specific CTLs was completely blocked by MHC I antibody, but not at all by MHC II antibody.
