{"product_id":"v5514-100ug","title":"CD21 Antibody","description":"\u003cp\u003eRecognizes a protein of 140kDa, which is identified as the complement receptor 2(CR2)\/CD21. This protein is expressed strongly on mature B cells, follicular dendritic cells and weakly on immature thymocytes and T lymphocytes. In B-cell ontogeny, CD21 appears after the pre-B-stage, is maintained during peripheral B-cell development and is lost upon terminal differentiation into plasma cells. CD21 expression is also gradually lost after stimulation of B cells in vitro.CD21 functions as receptor for C3d, C3dg and iC3b Complement components, for EBV and for IFNalpha.CD21 binds to CD23 and associates with CD19, CD81 and Leu13 to form a large signal-transduction complex involved in B cell activation.\u003c\/p\u003e","brand":"NSJ Bioreagents","offers":[{"title":"100 ug \/ Mouse","offer_id":46705184375008,"sku":"V5514-100UG","price":539.0,"currency_code":"KRW","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0601\/9330\/8896\/files\/get_image_dfd4e118-1a60-46dd-a54c-05cc43117edc.jpg?v=1733346837","url":"https:\/\/rndmate.com\/products\/v5514-100ug","provider":"알앤디메이트","version":"1.0","type":"link"}
