We have efficiently generated the first monoclonal antibody (MAb) against the human WIG-1 (wild-type p53-induced gene 1) protein, an apoptosis-related protein consisting of three zinc finger domains. Protein A affinity chromatography was performed to purify MAb from mice production ascites. Hybridomas were screened by indirect enzyme-linked immunosorbent assay (ELISA). One MAb designated GW-3E4 (IgG1), effective in detecting the nuclear protein in human esophageal squamous cell carcinoma (ESCC) tissues and EC109 cell line, was characterized by ELISA and Western immunoblotting. Thus, it binds to native WIG-1 protein and should be useful in studies of WIG-1 protein function and expression. By Western immunoblotting analysis of 20 patients with ESCC using the MAb, we found that the expression of WIG-1 protein in tumor tissue was significantly higher than in incision margin. The results showed that WIG-1 might be a novel modifier in esophageal carcinogenesis, and the WIG-1 MAb should be useful in further study of the mechanism in WIG-1-related physiological reactions.
