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.\u003c\/p\u003e\u003ch2\u003eCommon research applications\u003c\/h2\u003e\u003cul\u003e\u003cli\u003e\n\u003cstrong\u003eIHC:\u003c\/strong\u003e tissue distribution assessment; interpret with matched controls.\u003c\/li\u003e\u003c\/ul\u003e\u003ch2\u003eNotes for experimental interpretation\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eAccount for isoforms, paralogs, and post-translational modifications when interpreting signal.\u003c\/li\u003e\n\u003cli\u003eSupport specificity with biological controls (e.g., KO\/KD where available) and technical controls (e.g., secondary-only\/isotype).\u003c\/li\u003e\n\u003c\/ul\u003e\u003c!-- Sources (internal): - UniProt Knowledgebase (UniProt) – https:\/\/www.uniprot.org\/ - NCBI Gene (NIH\/NLM) – https:\/\/www.ncbi.nlm.nih.gov\/gene\/ - ZFIN – https:\/\/zfin.org\/ - Ensembl – https:\/\/www.ensembl.org\/ - Nature Methods (2015): A proposal for validation of antibodies – https:\/\/www.nature.com\/articles\/nmeth.3230 --\u003e","brand":"NSJ Bioreagents","offers":[{"title":"0.2 mg\/ml in 1X PBS with 0.1 mg\/ml BSA (US sourced), 0.05% sodium azide \/ 100 ug","offer_id":53046688055661,"sku":"V5514-100UG","price":559.0,"currency_code":"USD","in_stock":true},{"title":"0.2 mg\/ml in 1X PBS with 0.1 mg\/ml BSA (US sourced), 0.05% sodium azide \/ 20 ug","offer_id":53046841573741,"sku":"V5514-20UG","price":259.0,"currency_code":"USD","in_stock":true},{"title":"1 mg\/ml in 1X PBS; BSA free, sodium azide free \/ 100 ug","offer_id":53046841606509,"sku":"V5514SAF-100UG","price":559.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7424\/7277\/files\/get_image_7754505c-85e3-4047-9598-d589fc792521.jpg?v=1772010225","url":"https:\/\/www.ebiohippo.com\/products\/recombinant-cr2-antibody-complement-receptor-2-cd21-bha17133574","provider":"BioHippo","version":"1.0","type":"link"}
