As a monoclonal antibody, binding is driven by a single epitope, which can support consistent recognition but may be sensitive to epitope masking by PTMs or conformational changes.\u003c\/p\u003e\n\u003c!-- Sources (internal):\n- UniProtKB entry (P01876) — UniProt Consortium — https:\/\/www.uniprot.org\/uniprotkb\/P01876\/entry\n- NCBI Gene search ( Human IgA1) — NCBI — https:\/\/www.ncbi.nlm.nih.gov\/gene\/?term=+Human+IgA1\n- Ensembl search ( Human IgA1) — Ensembl — https:\/\/www.ensembl.org\/Multi\/Search\/Results?q=+Human+IgA1\n- PubMed search ( Human IgA1) — NLM — https:\/\/pubmed.ncbi.nlm.nih.gov\/?term=+Human+IgA1\n- Reactome pathway search ( Human IgA1) — Reactome — https:\/\/reactome.org\/content\/query?q=+Human+IgA1\n--\u003e","brand":"NSJ Bioreagents","offers":[{"title":"1 mg\/ml in PBS with 50% glycerol, 1% BSA and 0.09% sodium azide \/ 50 ug","offer_id":53043674186093,"sku":"R20183BTN-50UG","price":439.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7424\/7277\/files\/get_image_a681f890-a3f7-4aa2-abc1-ba71a6b803e4.jpg?v=1771934390","url":"https:\/\/www.ebiohippo.com\/products\/recombinant-human-iga1-antibody-biotin-conjugate-bha17103648","provider":"BioHippo","version":"1.0","type":"link"}
