Function
Mammaglobin-A also known as secretoglobin family 2A member 2 is a protein that in humans is encoded by the SCGB2A2 gene. SCGB2A2 is a member of the superfamily of secretoglobins, a group of small dimeric secreted and sometimes glycosylated proteins. Expressed mainly in mucosa, secretoglobins seem to be involved in cell signalling, immune response, and chemotaxis, and may also serve as transporters for steroid hormones in humans. SCGB2A2 expression is highly specific of mammary tissue, and is increasingly used for identification and detection of disseminated breast cancer cells. Mammaglobin is breast-associated glycoprotein distantly related to secretoglobin family that includes human uteroglobin and lipophilin. Anti-mammaglobin labels cytoplasm of normal breast epithelial cells as well as primary and metastatic breast carcinomas. Absence of mammaglobin expression is typically seen in prostate, kidney, colon, rectum, small intestine, stomach, pancreas, lung and thyroid tissue. Mammaglobin may be used as part of an immunohistochemical panel for determination of metastatic breast carcinoma and tumor of unknown primary origin.

Immunohistochemical analysis of paraffin-embedded human skin tissue with Mouse anti-Mammaglobin A antibody (HA601089) at 1/800 dilution.
The section was pre-treated using heat mediated antigen retrieval with Tris-EDTA buffer (pH 9.0) for 20 minutes. The tissues were blocked in 1% BSA for 20 minutes at room temperature, washed with ddH2O and PBS, and then probed with the primary antibody (HA601089) at 1/800 dilution for 1 hour at room temperature. The detection was performed using an HRP conjugated compact polymer system. DAB was used as the chromogen. Tissues were counterstained with hematoxylin and mounted with DPX. -
