{"product_id":"nsj-rq5551-100ug","title":"CD22 Antibody, 100 ug","description":"\u003cp\u003eCD22 is a surface glycoprotein of B lymphocytes that is rapidly phosphorylated on cytoplasmic tyrosines after antigen receptor cross-linking. It 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. And CD22 is located within the band region q13.1 of chromosome 19.\u003c\/p\u003e","brand":"NSJ Bioreagents","offers":[{"title":"100 ug","offer_id":51550123786520,"sku":"RQ5551","price":449.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0590\/5652\/1400\/files\/get_image_99a5f94d-6510-4660-b5b5-75bdaae5ece0.jpg?v=1768306313","url":"https:\/\/danabiosci.com\/products\/nsj-rq5551-100ug","provider":"Dana Bioscience","version":"1.0","type":"link"}
