Produktdetails anti-CD28 Antikörper

Spezifität: This antibody recognises the human CD28 cell surface antigen, a 44 kDa glycoprotein expressed by a subset of T lymphocytes. The antibody enhances the MLR response. 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.(2)

Aufreinigung: Affinity chromatography on Protein A.

Immunogen: Human peripheral blood T-cells.

Isotyp: IgG2b

Details zu CD28

Target: CD28

Andere Bezeichnung: CD28

Hintergrund: 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
