{"product_id":"nsj-v8638-20ug","title":"Recombinant CD22 Antibody \/ BL-CAM, 20 ug","description":"\u003cp\u003eRecognizes a protein of 130-140kDa, identified as CD22 (also known as BL-CAM). CD22 expression is restricted to normal and neoplastic B cells and is absent from other haemopoietic cell types. In B-cell ontogeny, CD22 is first expressed in the cytoplasm of pro-B and pre-B cells, and on the surface as B cells mature to become IgD+. It is not expressed by plasma cells, CD22 is found highly expressed in follicular mantle and marginal zone B-cells, and while germinal center B-cells are relatively weak. CD22 is a member of the immunoglobulin superfamily and serves as an adhesion receptor for sialic acid-bearing ligands expressed on erythrocytes and all leukocyte classes. It also associates with tyrosine kinases and play a role in signal transduction and B-cell activation.\u003c\/p\u003e","brand":"NSJ Bioreagents","offers":[{"title":"20 ug","offer_id":51548005302552,"sku":"V8638-20UG","price":259.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0590\/5652\/1400\/files\/get_image_3ba25faf-16f0-406d-8a21-16c0218a55d2.jpg?v=1768270939","url":"https:\/\/danabiosci.com\/products\/nsj-v8638-20ug","provider":"Dana Bioscience","version":"1.0","type":"link"}
