Human CD28 Antibody Product Information
Immunogen:Recombinant Human CD28 protein (Catalog#11524-H08H)
Clone ID:9H6E2
Ig Type:Mouse IgG1
Concentration:
Endotoxin:
Formulation:0.2 μm filtered solution in PBS with 5% trehalose
Preparation:This antibody was produced from a hybridoma resulting from the fusion of a mouse myeloma with B cells obtained from a mouse immunized with purified, recombinant Human CD28 (rh CD28; Catalog#11524-H08H; P10747-1; Met 1-Pro 152). The IgG fraction of the cell culture supernatant was purified by Protein A affinity chromatography.

            CD28/TP44 Background

            CD28 (Cluster of Differentiation 28) is a disulphide-bonded glycoprotein belonging to the immunoglobulin (Ig) superfamily, and structurally consists of a single Ig V-like extracellular domain, a transmembrane domain and an intracellular domain. Mouse CD28 is constitutively expressed on the surface of all murine T cells and on developing thymocytes as disulfide-linked homodimers or as monomers. CD28 can binds the B7-1 and B7-2 ligand, and together perform important functions in the T and B cell response pathways. B7/CD28 family members, which can augment or antagonize T-cell receptor signaling, in the regulation of central and peripheral T-cell tolerance. CD28 is thus involved in T-cell activation, the induction of cell proliferation and cytokine production and promotion of T-cell survival.
