{"product_id":"nsj-v8352-20ug","title":"CD4 Antibody, 20 ug","description":"\u003cp\u003eCD4 is a member of the Ig superfamily, primarily expressed on most thymocytes, a subset of T cells, and weakly on macrophages and dendritic cells. It acts as a coreceptor with the TCR during T cell activation and thymic differentiation by binding MHC class II and associating with the protein tyrosine kinase, lck. CD4 is expressed by the majority of thymocytes, most helper T cells, a subset of NK-T cells and weakly by dendritic cells and macrophages. CD4 plays an important role in the development of T cells and is required for mature T cells to function optimally.This antibody blocks helper T cell responses to MHC class II antigens, including cytolysis, proliferation, allogeneic B cell help, and release of lymphokines.\u003c\/p\u003e","brand":"NSJ Bioreagents","offers":[{"title":"20 ug","offer_id":51548038201624,"sku":"V8352-20UG","price":259.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0590\/5652\/1400\/files\/get_image_f5349752-f296-4f53-aa20-be1513066550.jpg?v=1768272001","url":"https:\/\/danabiosci.com\/products\/nsj-v8352-20ug","provider":"Dana Bioscience","version":"1.0","type":"link"}
