title: [Monoclonal antibody A12 against gastric cancer produced in immuno-reconstituted nude mice].
abstract: A monoclonal antibody (mAb) A12 against gastric cancer was prepared in immuno-reconstituted nude mice from human ductal adenocarcinoma of stomach, Sy86B. mAb A12 could react with the majority of gastric cancer tissues (24/27-88.9%) but only cross react with a few normal tissues tested. The corresponding antigen of mAb A12 (antigen A12) was expressed at higher levels and usually in more than 50% of the cancer cells. mAb A12 may be a valid preparation in targeting therapy of gastric cancer. Preliminary analysis of antigen A12 showed that it is a oncofetal antigen probably of glycolipid or glycoprotein in nature.
