{"product_id":"btk-antibody-bha17101792","title":"BTK Antibody","description":"\u003cp\u003eBTK plays a crucial role in B-cell ontogeny. This protein transiently phosphorylates GTF2I on tyrosine residues in response to B-cell receptor cross-linking. Defects in BTK are the cause of X-linked agammaglobulinemia type 1 (XLA). XLA is a humoral immunodeficiency disease which results in developmental defects in the maturation pathway of B-cells. Affected boys have normal levels of pre-B-cells in their bone marrow but virtually no circulating mature B-lymphocytes. This results in a lack of immunoglobulins of all classes and leads to recurrent bacterial infections like otitis, conjunctivitis, dermatitis, sinusitis or fatal sepsis or meningitis within the first years of life.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFormat:\u003c\/strong\u003e Purified\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NSJ Bioreagents","offers":[{"title":"In 1X PBS, pH 7.4, with 0.09% sodium azide \/ 0.08 ml","offer_id":53042911150445,"sku":"F50702-0.08ML","price":205.0,"currency_code":"USD","in_stock":true},{"title":"In 1X PBS, pH 7.4, with 0.09% sodium azide \/ 0.4 ml","offer_id":53042992808301,"sku":"F50702-0.4ML","price":439.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7424\/7277\/files\/get_image_47f854af-a02d-4f5c-b15f-f7ba53a216cc.jpg?v=1771923915","url":"https:\/\/www.ebiohippo.com\/products\/btk-antibody-bha17101792","provider":"BioHippo","version":"1.0","type":"link"}
