Description
The B-A38 monoclonal antibody specifically recognizes an extracellular epitope on human CD138 that is also known as Syndecan-1 (SDC-1). CD138 is a transmembrane type I and surface heparan sulfate proteoglycan that is expressed as an ~65-70 kDa core protein dimer with variable glycosylation. CD138 is encoded by SDC1 (syndecan 1) which belongs to the syndecan proteoglycan family. CD138 is expressed on pre-B cells, immature B cells, and plasma cells, but not on mature circulating B-lymphocytes, as well as by embryonic mesenchymal cells and certain epithelial and endothelial cells. It is strongly expressed on multiple-myeloma-derived cell lines and malignant plasma cell populations. CD138 is involved in many cellular functions including cell-cell and cell matrix adhesion. It binds to multiple extracellular matrix (ECM) proteins and soluble bioactive factors through its heparan sulfate side chains. ECM protein ligands for CD138 include fibronectin, certain collagens, tenascin, thrombospondin, and antithrombin III. Certain cytokines and growth factors are bound by CD138 and accumulated on CD138-positive cells which contributes to the sensitive recognition and response to these factors by neighboring cells. These may include fibroblast, hepatocyte, and epidermal growth factors and April. A soluble shed form of CD138 has also been described which can affect the stability and function of CD138.
BD® CompBeads can be used as surrogates to assess fluorescence spillover (compensation). When fluorochrome conjugated antibodies are bound to BD® CompBeads, they have spectral properties very similar to cells. However, for some fluorochromes there can be small differences in spectral emissions compared to cells, resulting in spillover values that differ when compared to biological controls. It is strongly recommended that when using a reagent for the first time, users compare the spillover on cells and BD® CompBeads to ensure that BD® CompBeads are appropriate for your specific cellular application.
The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography. The antibody was conjugated to the dye under optimum conditions and unreacted dye was removed. Store undiluted at 4°C and protected from prolonged exposure to light. Do not freeze.

2. Alexa Fluor® 488 fluorochrome emission is collected at the same instrument settings as for fluorescein isothiocyanate (FITC).
3. Source of all serum proteins is from USDA inspected abattoirs located in the United States.
4. Caution: Sodium azide yields highly toxic hydrazoic acid under acidic conditions. Dilute azide compounds in running water before discarding to avoid accumulation of potentially explosive deposits in plumbing.
5. This reagent has been pre-diluted for use at the recommended Volume per Test. We typically use 1 × 10^6 cells in a 100-µl experimental sample (a test).
