After reconstitution, the protein solution is stable at -20℃ for 3 months, at 2-8℃ for up to 1 week.\u003c\/p\u003e\n\n\u003cp\u003eBackground: CD81, belongs to the transmembrane 4 superfamily, also known as the tetraspanin family. Members of this family mediate signal transduction events that play a role in the regulation of cell development, activation, growth and motility. It is related to adhesion, morphology, activation, proliferation, and differentiation of B, T, and other cells. On B cells CD81 is part of a complex with CD21, CD19, and Leu13. This complex reduces the threshold for B cell activation via the B cell receptor by bridging Ag specific recognition and CD21-mediated complement recognition.\u003c\/p\u003e\n\n\u003cp\u003eSource: HEK293 cells\u003c\/p\u003e\n\n\u003cp\u003eTag: N-hFc\u003c\/p\u003e\n\n\u003cp\u003eFormulation: Lyophilized from a 0.22 μm filtered solution of PBS, pH 7.4.\u003c\/p\u003e\n\n\u003cp\u003eAntigen Sequence: FVNKDQIAKDVKQFYDQALQQAVVDDDANNAKAVVKTFHETLDCCGSSTLTALTTSVLKNNLCPSGSNIISNLFKEDCHQKIDDLFSGK\u003c\/p\u003e\n\n\u003cp\u003eEndotoxin: \u0026lt; 0.1 EU\/μg of the protein by LAL method.\u003c\/p\u003e\n\n\u003cp\u003eResearch Use Only\u003c\/p\u003e","brand":"ABclonal","offers":[{"title":"10ug","offer_id":45198271742131,"sku":"RP01871-10","price":196.0,"currency_code":"CAD","in_stock":true},{"title":"20ug","offer_id":45198271774899,"sku":"RP01871-20","price":266.0,"currency_code":"CAD","in_stock":true},{"title":"50ug","offer_id":45198271807667,"sku":"RP01871-50","price":280.0,"currency_code":"CAD","in_stock":true},{"title":"100ug","offer_id":45198271840435,"sku":"RP01871-100","price":448.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0305\/9482\/6376\/files\/download_8c66aff6-aaa8-42eb-a7a4-683d3483a9d3.png?v=1766959964","url":"https:\/\/afsbio.com\/products\/recombinant-human-cd81-protein-rp01871","provider":"AFSBio Inc.","version":"1.0","type":"link"}
