title: New monoclonal antibodies specific to HLA class I and their application in the study of acid treatment effect on cell surface antigens.
abstract: New monoclonal antibodies (mAbs) against HLA class I antigens were prepared and characterized. Three mAbs (CLI-1, CLI-2, CLI-3) were directed to the heavy chain of HLA class I molecules and one mAb (B2M-1) is specific to beta 2-microglobulin. Using these mAbs, it was confirmed that acid treatment selectively eliminated cell surface HLA class I antigenicity. The treatment with citric acid solution resulted in preparation of cells with lower residual HLA class I surface molecules than was seen after the treatment with glycine buffer.
