HLA抗原以低浓度存在于血浆中,但过去无HLA残留于血浆蛋白组分(PPF)中的直接证据。本研究试图通过中和HLA淋巴细胞毒抗体以检测PPF或白蛋白中有无HLA抗原。使用白蛋白和PPF各四批。选择10种不同的靶淋巴细胞以检测每一种血液制品中可能存在的10
HLA antigens are present in plasma at low concentrations but no direct evidence of HLA residue in the plasma protein fraction (PPF) in the past. This study attempted to detect the presence or absence of HLA antigens in PPF or albumin by neutralizing HLA lymphotoxin antibodies. Use each of four batches of albumin and PPF. Ten different target lymphocytes were chosen to test for the possible presence of 10 in each blood product
