CD44 antibodies, mouse

Clone: REA664 | Dilution: 1:10
Clone REA664 recognizes the mouse CD44 antigen, which is also known as Pgp-1, HCELL, HUTCH-I, HCAM, HERMES, or Ly-24. CD44 is a 80–95 kDa membrane glycoprotein and expressed by a variety of hematopoetic and non-hematopoetic cells. Different isoforms are generated by alternative splicing. Clone REA664 reacts with all isoforms and both allelic forms of CD44. CD44 functions as a receptor for hyaluronic acid (HA) and mediates cell-cell and cell-matrix interactions through its affinity for HA, and possibly also through its affinity for other ligands, such as osteopontin, collagens, and matrix metalloproteinases (MMPs). The interaction between galectin-9 and CD44 increases the stability and function of adaptive regulatory T cells. CD44 expression is upregulated on naive T cells upon activation and high CD44 expression is maintained on memory T cells. Therefore, CD44 is often used to discriminate CD44
antigen–experienced T cells from CD44
) naive T cells.
Additional information: Clone REA664 displays negligible binding to Fc receptors.
