Primarily located in endothelial and phagocytic cells, FcRn binds to IgG in acidic endosomes, recycling them back to the cell surface and releasing them into circulation at a neutral pH. This unique pH-dependent binding mechanism protects IgG from lysosomal degradation, significantly extending its serum half-life. Additionally, FcRn mediates the transcytosis of IgG across placental and epithelial barriers, facilitating passive immunity from mother to offspring and mucosal immune defense. Its role makes it a major therapeutic target for modulating antibody-based therapies.\u003c\/p\u003e\u003c\/div\u003e","brand":"Starter","offers":[{"title":"10μg","offer_id":42332837511243,"sku":null,"price":170.0,"currency_code":"USD","in_stock":true},{"title":"25μg","offer_id":42332837544011,"sku":null,"price":300.0,"currency_code":"USD","in_stock":true},{"title":"50μg","offer_id":42332837576779,"sku":null,"price":470.0,"currency_code":"USD","in_stock":true},{"title":"100μg","offer_id":42332837609547,"sku":null,"price":785.0,"currency_code":"USD","in_stock":true},{"title":"500μg","offer_id":42332837642315,"sku":null,"price":2420.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0590\/8375\/1499\/files\/c62f247e-17ec-49e0-9a33-ef81e898e6d4.png?v=1776077994","url":"https:\/\/www.antbioinc.com\/products\/human-fcgrtb2m-heterodimer-protein-his-tag-s0a6075","provider":"AntBio","version":"1.0","type":"link"}
