Produktdetails anti-CD28 Antikörper (Biotin)

Target: CD28

Reaktivität: Maus

Wirt: Golden Syrian Hamster

Klonalität: Monoklonal

Konjugat: Dieser CD28 Antikörper ist konjugiert mit Biotin

Applikation: Flow Cytometry (FACS)

Marke: BD Pharmingen™

Produktmerkmale: The 37.51 antibody reacts with CD28, which is expressed on most thymocytes, at low density on nearly all CD4+ and CD8+ peripheral T cells, and at even lower density on NK cells. The expression of CD28, in splenocytes and thymocytes, has been reported to increase after activation. CD28 transcripts are found in mast cells, and cell-surface expression of CD28 is induced upon maturation or activation of mast cells. It has been reported that CD28 is not expressed on some populations of intraepithelial T lymphocytes. CD28 is a costimulatory receptor, its ligands include CD80 (B7-1) and CD86 (B7-2). The 37.51 mAb augments proliferation and cytokine production by activated T and NK cells and can provide a costimulatory signal for CTL induction. There is considerable evidence that CD28 is a costimulatory receptor involved in many, but not all, T cell-dependent immune responses. This antibody is routinely tested by flow cytometric analysis. Other applications were tested during antibody development only or reported in the literature. Two-color analysis of CD28 expression on splenic T lymphocytes. After pre-incubation with purified anti-mouse CD16/CD32 mAb 2.4G2 [Mouse BD Fc Block™] (Cat. No. 553141), BALB/c splenocytes were simultaneously stained with FITC-conjugated anti-mouse CD4 mAb RM4-5 (Cat. No. 553046) and FITC-conjugated anti-mouse CD8a mAb 53-6.7 (Cat. No. 553030), in addition to staining with biotinylated anti-mouse CD28 clone 37.51 (right panel), followed by streptavidin-PE (Cat. No. 554061). Flow cytometry was performed on a BD FACScan™ flow cytometry system.

Anwendungsinformationen

Applikationshinweise: Flow Cytometry : For flow cytometry of cell suspensions from peripheral lymphoid tissues, it is recommended that multicolor staining be performed to identify T lymphocytes and/or NK cells and that purified anti-mouse CD16/CD32 mAb 2.4G2 [Mouse BD Fc Block™] be used. Since this antigen is expressed at low density on resting peripheral T lymphocytes, it is recommended that a "bright" second-step reagent, such as Streptavidin-PE , be used for flow cytometric staining of these cell populations.
