No azide/low endotoxin: Aqueous buffered solution containing no preservative, 0.2µm sterile filtered. Endotoxin level is ≤0.1 EU/µg (≤0.01 ng/µg) of protein as determined by the LAL assay.

Preparation And Storage

Store undiluted at 4°C. The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography. This preparation contains no preservatives, thus it should be handled under aseptic conditions.

Product Notices

  1. Since applications vary, each investigator should titrate the reagent to obtain optimal results.
  2. An isotype control should be used at the same concentration as the antibody of interest.
  3. Although hamster immunoglobulin isotypes have not been well defined, BD Biosciences Pharmingen has grouped Armenian and Syrian hamster IgG monoclonal antibodies according to their reactivity with a panel of mouse anti-hamster IgG mAbs. A table of the hamster IgG groups, Reactivity of Mouse Anti-Hamster Ig mAbs, may be viewed at

The H9.2B8 antibody reacts with the 140-kDa integrin αv chain (CD51). Heterodimers of CD51 with several integrin β chains function as receptors for extracellular matrix (ECM) proteins. CD51/CD61 (αvβ3 integrin, vitronectin receptor) mediates adhesion to fibronectin, fibrinogen, vitronectin, thrombspondin, von Willebrand factor, and CD31 (PECAM-1).  It is expressed on activated T lymphocytes, polymorphonuclear granulocytes, blastocysts, and osteoclasts. We have been unable to detect CD51 on mouse platelets using either mAb H9.2B8 or RMV-7.  CD51 also forms heterodimers with integrin β1 (CD29) and β5, β6, and α8 chains. αv integrins have diverse functions in development and homeostasis.  H9.2B8 antibody binds to an epitope of CD51 near or at the receptor-ligand binding site(s), as evidenced by its ability to synergistically participate in blocking of the adherence of vitronectin receptor-bearing cells to ECM proteins.  This hamster mAb to a mouse leukocyte antigen does not cross-react with rat leukocytes.

NA/LE refers to the culture and purification methods and buffer used to produce purified antibodies with no azide and low endotoxin: Aqueous buffered solution containing no preservative, 0.2µm sterile filtered. Endotoxin level is ≤0.01 EU/µg (≤0.001 ng/µg) of protein as determined by the LAL assay.NA/LE are perfectly suited to be used in culture or in vivo (for nonhuman studies) for functional assays — blocking, neutralizing, activation or depletion — where the presence of azide may damage cells or exogenous endotoxin may signal or activate cells.
