Mature human SLAMF3 consists of a 407 amino acid (aa) extracellular domain (ECD) with two Ig-like V-set and two Ig-like truncated C2-set domains. The ECD of human SLAMF3 shares 57% - 59% aa sequence identity with mouse and rat SLAMF3. Within the first two Ig-like domains that are common to all SLAM proteins, human SLAMF3 shares 24% - 39% aa sequence identity with human 2B4, BLAME, CD2F-10, CD84, CRACC, NTB-A, and SLAM. It is expressed on T and B cells, thymocytes, and more weakly on NK cells. It may participate in adhesion reactions between T lymphocytes and accessory cells by homophilic interaction. Promotes T-cell differentiation into a helper T-cell Th17 phenotype leading to increased IL-17 secretion; the costimulatory activity requires SH2D1A. SLAMF3 may be involved in the maintenance of peripheral cell tolerance by serving as a negative regulator of the immune response. It also disable autoantibody responses and inhibit IFN-gamma secretion by CD4+ T-cells and negatively regulate the size of thymic innate CD8+ T-cells and the development of invariant natural killer T (iNKT) cells.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eConcentration\u003c\/b\u003e: \u003c\/p\u003e\u003cp\u003e\u003cb\u003eActivity\u003c\/b\u003e: Not validated for activity\u003c\/p\u003e\u003cp\u003e\u003cb\u003eSequence\u003c\/b\u003e: Lys48-Lys454\u003c\/p\u003e\u003cp\u003e\u003cb\u003ePurity\u003c\/b\u003e:  \u0026gt; 95 % as determined by reducing SDS-PAGE.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFormulation\u003c\/b\u003e: Lyophilized from a 0.2 μm filtered solution of PBS, pH 7.4.\u003cbr\u003eNormally 5% - 8% trehalose, mannitol and 0.01% Tween 80 are added as protectants before lyophilization.\u003cbr\u003ePlease refer to the specific buffer information in the printed manual.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eReconstitution\u003c\/b\u003e: Please refer to the printed manual for detailed information.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eEndotoxin\u003c\/b\u003e:  \u0026lt; 1.0 EU per μg of the protein as determined by the LAL method.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eCalculated MW\u003c\/b\u003e: 45.6 kDa\u003c\/p\u003e\u003cp\u003e\u003cb\u003eObservedMW\u003c\/b\u003e: 75 kDa\u003c\/p\u003e","brand":"GeneBio Systems","offers":[{"title":"Default Title","offer_id":47982484291684,"sku":"PKSH033121","price":356.4,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0558\/8588\/9636\/files\/no_image_default_image-jpeg_18b10823-8a9d-40d0-ab43-b8e63bf45956.jpg?v=1772386703","url":"https:\/\/www.genebiosystems.com\/products\/recombinant-human-slamf3-cd229-protein-his-tag","provider":"GeneBio ","version":"1.0","type":"link"}
