Data Images
Immobilized Recombinant Mouse CD8 alpha (Catalog # 9135-CD) supports the adhesion of Jurkat human acute T cell leukemia cells. The ED50 for this effect is 1-5 μg/mL.
Background: CD8
CD8, also known as Ly-2 or Leu-2, is a heterodimeric glycoprotein (alpha and beta subunits) that functions in conjunction with the T cell receptor in the recognition of MHC class I/peptide complexes (1, 2). CD8 alpha is expressed on double positive (CD4+CD8+) thymocytes and mature CD8+ cytolytic T cells (CTL) (3-5), intraepithelial lymphocytes (IEL) (6), some gamma-delta T cells (7), subsets of thymic and splenic dendritic cells (DC) (8), and peritoneal mast cells (9). It can form disulfide linked homodimers or heterodimers with CD8 beta (10). Thymic CD8+ DC express primarily alpha beta heterodimers, while splenic CD8+ DC primarily express alpha alpha homodimers (8). CD8 alpha + DC can present viral antigenic peptides in complex with MHC I and prime CTL responses (11). The approximately 35 kDa mature mouse CD8 alpha consists of a 169 amino acid (aa) extracellular domain (ECD) with one Ig-like domain, a 21 aa transmembrane segment, and a 30 aa cytoplasmic domain (12). Within the ECD, mouse CD8 alpha shares 49% and 64% aa sequence identity with human and rat CD8 alpha, respectively.
