NAMRU mouse mammary gland epithelial cell line NMuMG

The 281-2 monoclonal antibody specifically binds to the core protein of CD138 (Syndecan-1), a cell-surface, integral membrane heparan sulfate- and chondroitin sulfate-containing proteoglycan that binds to interstitial extracellular matrix molecules.  Syndecan-1 is predominantly expressed on epithelial cells, where its expression correlates with normal epithelial organization.  It is also expressed on B lymphocytes at specific stages during their differentiation: precursor B cells in the bone marrow, and antibody-secreting cells including plasma cells (but not mature peripheral B cells).  It is thus implicated in mediating B cell-matrix interactions.  CD138 expression is also regulated during embryonic development, and the molecule shows a tissue- specific structural polymorphism resulting from different post-translational  modifications.  The 281-2 antibody may be used to detect the differently glycosylated forms, because it reacts with the core protein.  Furthermore, the mAb detects the Syndecan-1 ectodomain which is cleaved from cell surfaces by a metalloproteinase. This antibody is routinely tested by flow cytometric analysis. Other application were tested at BD Biosciences Pharmingen during development only or reported in the litererature.
