title: Cloning expression, monoclonal antibody preparation and serologic study of mammaglobin in breast cancer.
abstract: Mammaglobin may be a potential serum biomarker for the differential diagnosis of breast cancer. 260 serum samples were collected from 127 untreated breast cancer patients and 133 healthy volunteers to analyze the sera expression of mammaglobin and its implications for both. The expression vector of pGEX-4T-2-Mammaglobin and pBVIL1-Mammaglobin were constructed and transformed into E.coli.HB101 for expression. The mice were immunized with the purified recombinant protein to prepare monoclonal antibody and to detect by ELISA the serum of normal people and breast cancer patients. Recombinant mammaglobin antigen was effectively expressed in E.coli. Two hybridoma cell lines were obtained after the mice were immunized by pGEX-4T-2-mammaglobin. 133 cases of normal serum and 127 cases of breast cancer serum were analyzed by ELISA. The sera expression level of mammaglobin in breast cancer group (average OD value 0.645±0.223) was significantly (p
