A method of determining the human cancer antigen level in a serum sample by sandwich-technique enzyme immunoassay which comprises using, as the first antibody, a mixture of anti-human pulmonary adenocarcinoma monoclonal antibody ALC-186 and anti-human gastric cancer monoclonal antibody AMC-462 or a mixture of anti-human pulmonary adenocarcinoma monoclonal antibody ALC-186 and anti-human pulmonary squamous cell carcinoma monoclonal antibody SLC-454, immobilizing said first antibody on a solid phase, allowing a human serum sample to contact with said first antibody for causing a cancer antigen or antigens in the serum to be bound to said first antibody, then allowing a mixture of peroxidase-labeled anti-human pulmonary adenocarcinoma monoclonal antibody ALC-186 and β-galactosidase-labeled anti-human gastric cancer monoclonal antibody AMC-462, when the first antibody is a mixture of anti-human pulmonary adenocarcinoma monoclonal antibody ALC-186 and anti-human gastric cancer monoclonal antibody AMC-462, or a mixture of peroxidase-labeled anti-human pulmonary adenocarcinoma monoclonal antibody ALC-186 and β-galactosidase-labeled anti-human pulmonary squamous cell carcinoma monoclonal antibody SLC-454, when the first antibody is a mixture of anti-human pulmonary adenocarcinoma monoclonal antibody ALC-186 and anti-human pulmonary squamous cell carcinoma SLC-454, which is used each as the second antibody, to be bound to said cancer antigen or antigens, assaying the thus-bound β-galactosidase-labeled second antibody by addition of a substrate for β-galactosidase followed by enzyme activity measurement, and then assaying the bound peroxidase-labeled second antibody by addition of a substrate for peroxidase followed by enzyme activity measurement.
一种通过夹心技术酶免疫测定法测定血清样品中人类癌症抗原水平的方法,该方法包括使用以下抗体作为第一抗体、抗人肺腺癌单克隆抗体 ALC-186 和抗人胃癌单克隆抗体 AMC-462 的混合物,或抗人肺腺癌单克隆抗体 ALC-186 和抗人肺鳞癌单克隆抗体 SLC-454 的混合物、将所述第一抗体固定在固相上,让人血清样品与所述第一抗体接触,使血清中的一种或多种癌症抗原与所述第一抗体结合,然后让过氧化物酶标记的抗人肺腺癌单克隆抗体 ALC-186 和β-半乳糖苷酶标记的抗人胃癌单克隆抗体 AMC-462 的混合物与所述第一抗体结合、当第一抗体是抗人肺腺癌单克隆抗体 ALC-186 和抗人胃癌单克隆抗体 AMC-462 的混合物,或过氧化物酶标记的抗人肺腺癌单克隆抗体 ALC-186 和 β-半乳糖苷酶标记的抗人肺鳞癌单克隆抗体 SLC-454 的混合物、当第一抗体是抗人肺腺癌单克隆抗体 ALC-186 和抗人肺鳞状细胞癌单克隆抗体 SLC-454 的混合物时、当第一抗体是抗人肺腺癌单克隆抗体 ALC-186 和抗人肺鳞状细胞癌 SLC-454 的混合物时,第二抗体是抗人肺腺癌单克隆抗体 ALC-186 和抗人肺鳞状细胞癌 SLC-454 的混合物。
