Rat SD, also known as Sprague-Dawley (outbred) IgG1, κ
Mouse (BALB/c) IL-2-activated killer (LAK) Cells
Flow cytometry (Routinely Tested), Blocking, Immunoprecipitation (Reported)
1.0 mg/ml
No azide/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.

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.

Recommended Assay Procedures

Flow cytometry:  Investigators may wish to consider using a second-step reagent conjugated to a "bright" fluorochrome, such as PE Goat Anti-Rat Ig (Cat. No. 550767), as CD51 may be expressed at low density on the cell surface.

Product Notices

  1. Since applications vary, each investigator should titrate the reagent to obtain optimal results.
  2. Please refer to for technical protocols.

The RMV-7 monoclonal antibody specifically binds to CD51, the 140 kDa integrin αV chain. Heterodimers of CD51 with several integrin β chains function as receptors for extracellular matrix proteins. CD51/CD61 (αVβ3 integrin, vitronectin receptor) mediates adhesion to fibronectin, fibrinogen, vitronectin, thrombospondin, von Willebrand factor, and CD31 (PECAM-1). CD51 is expressed on activated T lymphocytes, polymorphonuclear granulocytes, blastocysts, and osteoclasts. CD51 is reportedly not detectable on mouse platelets using either H9.2B8 or RMV-7 antibody clones. CD51 also forms heterodimers with CD29 (integrin β1), integrins β5, β6, and β8 chains. αV integrins have diverse functions in development and homeostasis. The RMV-7 antibody reportedly blocks LAK-cell binding to vitronectin, fibronectin, fibrinogen, and CD31. Furthermore, the RMV-7 antibody reportedly inhibits LAK-cell cytoxicity against certain target cells by interfering with the binding of LAK cells to their target cells.

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.
