Anti-Mammaglobin A / SCGB2A2, clone MSVA-457R

Antibody in 1X PBS with 0.05% BSA, 0.05% sodium azide. Mammaglobin A (SCGB2A2) is a secreted glycoprotein encoded by the SCGB2A2 gene and is a member of the secretoglobin family of small secreted proteins expressed in epithelial tissues. Mammaglobin A Antibody for IHC enables immunohistochemistry detection of this breast-associated protein in formalin-fixed paraffin-embedded tissue sections and is widely used to study mammary epithelial differentiation and breast tumor biology. In immunohistochemistry studies, Mammaglobin A staining is commonly used as a marker of breast epithelial origin because of its strong expression in mammary gland tissue and frequent detection in breast carcinomas.Mammaglobin A is primarily produced by luminal mammary epithelial cells and is secreted into the luminal spaces of glandular structures. In immunohistochemistry staining of normal breast tissue, Mammaglobin A Antibody for IHC typically reveals cytoplasmic staining of ductal and lobular epithelial cells, reflecting the secretory localization of this protein. Non-epithelial stromal components of breast tissue generally show little to no staining, allowing clear visualization of mammary epithelial compartments within tissue sections.Mammaglobin A antibody, also referred to as SCGB2A2 antibody or Mammaglobin antibody in the literature, detects a protein that is frequently used in immunohistochemistry panels for identifying tumors of breast origin. In breast carcinoma specimens, Mammaglobin A Antibody for IHC commonly produces cytoplasmic staining of malignant epithelial cells. This staining pattern helps highlight tumor cell populations and supports studies examining breast tumor differentiation and metastatic disease.Immunohistochemistry analysis across a wide range of tissues demonstrates that Mammaglobin A expression is largely restricted to breast epithelium, with minimal staining observed in most other normal tissues. Consistent with this distribution, Mammaglobin A expression is frequently detected in breast carcinomas, while most non-breast tumor types show little or no staining. These patterns make Mammaglobin A a useful marker for studying breast-derived epithelial cells and breast cancer samples in research settings.Mammaglobin A Antibody for IHC (clone MSVA-457R), a recombinant rabbit monoclonal antibody, has been tested on extensive panels of normal and cancer tissue microarrays. The immunohistochemistry staining patterns observed with this antibody across multiple tissues align with expression profiles reported in the Human Protein Atlas. Nuclear counterstain and chromogenic signal patterns highlight epithelial cell populations and breast tumor cells consistent with known Mammaglobin A expression in mammary tissue.This antibody is also part of a broader collection of IHC antibodies validated by tissue microarray analysis, supporting consistent staining across normal and cancer tissues.
