{"product_id":"r30191","title":"CD22 Antibody","description":"\u003cp\u003eCD22 is a surface glycoprotein of B lymphocytes that is rapidly phosphorylated on cytoplasmic tyrosines after antigen receptor cross-linking. CD22 is a negative regulator of antigen receptor signaling whose onset of expression at the mature B cell stage may serve to raise the antigen concentration threshold required for B cell triggering. The human CD22 gene is expressed specifically in B lymphocytes and likely has an important function in cell-cell interactions. The B cell coreceptor CD22 plays an important role in regulating signal transduction via the B cell Ag receptor.3 CD22 is located within the band region q13.1 of chromosome 19.\u003c\/p\u003e","brand":"NSJ Bioreagents","offers":[{"title":"100 ug \/ Rabbit","offer_id":49476848025880,"sku":"R30191","price":439.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0590\/5652\/1400\/files\/get_image_de4625c1-db99-41e0-bf00-328ac62ec06e.jpg?v=1734484888","url":"https:\/\/danabiosci.com\/products\/r30191","provider":"Dana Bioscience","version":"1.0","type":"link"}
