Description
The BMA-12 monoclonal antibody specifically binds to CD100 which is also known as, Semaphorin-4D (Sema4D), or Collapsin-4 (Coll-4). CD100 is a ~150 kDa type I transmembrane glycoprotein that belongs to the class IV Semaphorin subfamily within the Ig gene superfamily. CD100 is expressed by cells from a broad range of tissues including the nervous system, where it serves in axon guidance and synapse formation, and the kidney. It is expressed by most hematopoietic cells including T cells which express CD100 more abundantly than B cells and dendritic cell subsets. Its expression is significantly upregulated upon activation of these cell types. CD100 can costimulate T cell responses. For B cells and dendritic cells, CD100 interaction with its ligands, CD72 or Plexin B1, induces cellular activation and promotes survival, respectively. CD100 is also known to interact with Plexin B2 on skin gamma delta T cells and contribute to the repair of tissue damage caused by inflammation. A biologically-active, soluble form of CD100 is generated by proteolytic cleavage of the cell surface form.
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.
Store undiluted at 4°C and protected from prolonged exposure to light. Do not freeze. The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography. The antibody was conjugated to the dye under optimum conditions that minimize unconjugated dye and antibody.

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. Since applications vary, each investigator should titrate the reagent to obtain optimal results.
6. The production process underwent stringent testing and validation to assure that it generates a high-quality conjugate with consistent performance and specific binding activity. However, verification testing has not been performed on all conjugate lots.
7. Please observe the following precautions: We recommend that special precautions be taken (such as wrapping vials, tubes, or racks in aluminum foil) to protect exposure of conjugated reagents, including cells stained with those reagents, to any room illumination. Absorption of visible light can significantly affect the emission spectra and quantum yield of tandem fluorochrome conjugates.

9. An isotype control should be used at the same concentration as the antibody of interest.
