产品信息
抗原名称

宿主
Mouse BALB/c IgG2a, κ
免疫原
Human CTLA4 Recombinant Protein
简单描述
The BNI3 monoclonal antibody specifically binds to the human cytolytic T lymphocyte-associated antigen (CTLA-4), also known as CD152. CTLA-4 is transiently expressed on activated CD28+ T cells and binds to CD80 and CD86 present on antigen presenting cells (APC) with high avidity. This interaction appears to deliver a negative regulatory signal to the T cell. Recent reports indicate that CTLA-4 is also expressed on B cells when cultured with activated T cells, suggesting a role for CTLA-4 in the regulation of B-cell response. Immobilized BNI3 antibody enhances T-cell proliferation induced by antibody-mediated crosslinking of CD3 and CD28. Recent studies have shown that CD152 can be expressed by regulatory T (Treg) cells. After cellular fixation and permeabilization, the BNI3 antibody can stain intracellular CD152 expressed in T cells including Treg cells. Clone BNI3 was studied in the VI Leukocyte Typing Workshop.

产品详情
Biotin
Biotin is a ubiquitous co-factor (also known as Vitamin B7) that has many properties that make it extremely useful for molecular biology. Biotin has an extremely high affinity for the Avidin family of proteins (Kd = 10-15 M), making it the perfect tool to link two molecules. Biotin labeled antibodies can be combined with any number of Avidin-conjugated probes in order to customize an assay to a particular need. This is especially useful in the case of magnetic cell separation using streptavidin/magnetic bead conjugates, or in the case of flow cytometry using streptavidin/fluorophore conjugates.

Flow cytometric analysis of CD152 expression on stimulated human peripheral mononuclear cells. Peripheral blood mononuclear cells were stimulated with concanavalin A for 3 days, then stained with either Biotin Mouse IgG2a, κ Isotype Control (Cat. No. 555572; dashed line histogram) or Biotin Mouse Anti-Human CD152 (Cat. No. 555852; solid line histogram), followed by PE Streptavidin (Cat. No. 554061). The fluorescence histograms were derived from gated events with the forward and side light-scattering characteristics of viable activated cells. Flow cytometry was performed on a BD FACScan™ system.
