CD28 antibody (PE)

Catalog No. ABIN118584

Product Details anti-CD28 Antibody (PE)

Target: CD28

Reactivity: Human

Host: Rat

Clonality: Monoclonal

Conjugate: This CD28 antibody is conjugated to PE

Application: Flow Cytometry (FACS)

Specificity: This antibody recognises the human CD28 cell surface antigen, a 44 kDa glycoprotein expressed by a subset of T lymphocytes. It has been reported that this clone also recognises an epitope of CD28 expressed by NK cells, which is not recognised by clones of 9.3 or CD28.2.

Purification: Affinity chromatography on Protein G.

Immunogen: Human peripheral blood T-cells. Spleen cells from an immunised DA rat were fused with cells of the Y3/Ag 1.2.3 rat myeloma cell line.

Clone: YTH913-12

Isotype: IgG2b

Background: Human CD28 antigen is a 44 kDa disulfide linked homodimeric T cell specific surface glycoprotein. It is a cell adhesion molecule of the immunoglobulin superfamily which is constitutively expressed on most peripheral blood T lymphocytes (approximately 95 % of CD4+ cells and 50 % of CD8+ cells). Mature thymocytes exhibit higher levels of CD28 than the immature cells. Activation of T cells results in enhanced CD28 expression. T cell activation requires two combined signals provided by antigen presenting cells. The first is mediated via the T cell receptor following its interaction with antigenic peptide MHC complexes, and the second is delivered by accessory or costimulating molecules through their counter receptors on T lymphocytes. CD28 bears structural homology to CTLA 4 which is expressed at very low levels on the surface of CD4+ and CD8+ peripheral blood cells only following activation. CD28 is the natural receptor for the B7/BB 1 ligand (CD80) a 55-60 kDa glycoprotein which is expressed on activated B lymphocytes, on dendritic cells and on interferon gamma treated monocytes. The binding of B7 1/BB 1 Molecules to CD28 is involved in T lymphocyte activation and in the initiation and maintenance of chronic inflammation.Synonyms: T-cell-specific surface glycoprotein CD28, TP44
