CD40 antibody (Extracellular Domain)

Catalog No. ABIN118123

Product Details anti-CD40 Antibody

Target: CD40

Binding Specificity: Extracellular Domain

Reactivity: Mouse

Host: Rat

Clonality: Monoclonal

Conjugate: This CD40 antibody is un-conjugated

Application: Flow Cytometry (FACS), Immunohistochemistry (Frozen Sections) (IHC (fro)), Enzyme Immunoassay (EIA)

Specificity: Specificity was checked by ELISA and flow cytometry using BHK cells transfected with mouse CD40. It does not react with normal mouse Ig or with human IgG1 and will stain most mature mouse B cells. It does not cross react with mouse T cells. Clone 3/23 is a powerful activator of normal B cells especially in the presence of IL-4.

Purification: Affinity chromatography on Protein G

Immunogen: Extracellular Domain of Mouse CD40 and the Fc portion of Human IgG1. Spleen cells from immunised LOU/c rats were fused with cells of the Ag8 mouse myeloma cell line.

Clone: 01-03-23

Isotype: IgG2a

Target Details for CD40

Target: CD40

Alternative Name: CD40 (CD40 Products)

Background: CD40 (48 to 50 kDa) is a transmembrane glycoprotein mainly expressed on the surface of B cells and also expressed on monocytes, dendritic cells, and thymic epithelium. CD40 is a member of the tumor necrosis factor (TNF) receptor superfamily, which includes the low affinity nerve growth factor (NGF) receptor and CD95/Fas. CD40 is the receptor for CD40 ligand. CD40 ligand (CD40L, CD154, gp39, and TRAM) belongs to the TNF gene family and is expressed more widely than CD40 predominantly on activated CD4+ T cells. Following interaction with CD40 ligand, CD40 mediates a number of major immunoregulatory functions, central to the control of thymus dependent humoral immunity and may be critical in the development of cell mediated immune responses. Other biological actions include B cell homotypic adhesion, proliferation, immunoglobulin isotype switch, and secretion. Activation of CD40 has also been shown to inhibit the growth of certain B cell lymphomas and to induce the death of transformed cells of mesenchymal or epithelial origin.Synonyms: B-cell surface antigen CD40, Bp50, CD40L receptor, CDw40, TNFRSF5, Tumor necrosis factor receptor superfamily member 5
