CD46 is expressed by all cells except erythrocytes. CD46 has cofactor activity for inactivation of complement components C3b and C4b by serum factor I, which protects the host cell from damage by complement. It may be involved in the fusion of the spermatozoa with the oocyte during fertilization. CD46 also acts as a costimulatory factor for T-cells which induces the differentiation of CD4+ into T-regulatory 1 cells. T-regulatory 1 cells suppress immune responses by secreting interleukin-10, and therefore are thought to prevent autoimmunity. A number of viral and bacterial pathogens exploit this property and directly induce an immunosuppressive phenotype in T-cells by binding to CD46. CD46 acts as a receptor for the Edmonston strain of measles virus, human herpesvirus-6, and type IV pili of pathogenic Neisseria.\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: Cys35-Asp328\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 20mM PB, 150mM NaCl, 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: 33.8 kDa\u003c\/p\u003e\u003cp\u003e\u003cb\u003eObservedMW\u003c\/b\u003e: 50-65 kDa\u003c\/p\u003e","brand":"GeneBio Systems","offers":[{"title":"Default Title","offer_id":47978878337124,"sku":"PKSH032220","price":300.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0558\/8588\/9636\/files\/no_image_default_image-jpeg_b39c12cf-7eab-4cc1-8526-2e506e6f7ba0.jpg?v=1772294954","url":"https:\/\/www.genebiosystems.com\/en-us\/products\/recombinant-human-cd46-protein-his-tag","provider":"GeneBio ","version":"1.0","type":"link"}
