{"product_id":"f50702-0-08ml","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","brand":"NSJ Bioreagents","offers":[{"title":"0.08 ml \/ Rabbit","offer_id":49477785125144,"sku":"F50702-0.08ML","price":199.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0590\/5652\/1400\/files\/get_image_56e03e3e-83d8-46da-890f-41a8a500c77d.jpg?v=1734498509","url":"https:\/\/danabiosci.com\/products\/f50702-0-08ml","provider":"Dana Bioscience","version":"1.0","type":"link"}
