Specifications for CD229 (Ly-9) Antibody, anti-mouse, REAfinity™


Clone REA273 recognizes both mouse CD229 antigen alleles, Ly9.1 and Ly9.2. CD229 is a glycoprotein of the SLAM family also known as Ly9 or SLAMF3 which is a homophilic cell surface receptor present on a variety of immune cell types including T cells, B cells, NK cells, and thymocytes. It has been shown to interact with the adaptor proteins, SLAM-associated protein and EAT-2. CD229 is highly expressed on innate-like lymphocytes such as iNKT cells and in contrast to SLAMF1 and SLAMF6, CD229 plays a negative rather than a positive role in the signaling pathways required for innate-like lymphocyte development in the thymus.
Additional Information: Clone REA273 displays negligible binding to Fc receptors.
