摘要
A practical mixed hemadsorption assay (MHA) was developed for the detection of cell surface binding anti-tumor antigen antibodies (anti-TA Ab) in the human sera. The assay was compared to enzyme-linked immunosorbent assay (ELISA) and dot ELISA in the detection of the antibodies developed against GA733-2 antigen. SW1116 cell line and recombinant GA733-2E protein were used as targets in the MHA and solid phase immunoassays (SPIA), respectively. Sera were obtained from healthy donors and vaccinated-colon carcinoma patients. The sensitivity level of the MHA was very high for detection of anti-TA Ab in sera. (C) 2002 Elsevier Science B.V.
