{"product_id":"new-product-284445","title":"CD21 monoclonal antibody","description":"\u003cp\u003eComplement receptor type 2 (CD21\/CR2) is a type 1 transmembrane glycoprotein whose expression is largely restricted to B lymphocytes and follicular dendritic cells. Research studies have shown that CD21\/CR2 functions to bind the complement fragments iC3b, C3dg, and C3d, which function to activate the alternative complement pathway and MAC formation. In addition to its function as a complement receptor, CD21\/CR2 also functions as the B lymphocyte receptor for Epstein-Barr virus and interferon alpha. Research studies have also shown that CD21\/CR2 participates in B cell activation, proliferation, and protection from apoptosis through its association with components of the B cell coreceptor signaling complex such as CD19 and CD21.\u003c\/p\u003e","brand":"ABCbiolab","offers":[{"title":"100ul \/ Mouse \/ Human","offer_id":45809841602840,"sku":"ABCBW12535","price":325.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0590\/5652\/1400\/products\/758-7580448_monoclonal-antibody-png-transparent-png_db51be1f-010c-4fa5-a2e0-bb5baccab14f.png?v=1689761603","url":"https:\/\/danabiosci.com\/products\/new-product-284445","provider":"Dana Bioscience","version":"1.0","type":"link"}
