{"product_id":"new-product-224725","title":"CD8B polyclonal antibody","description":"\u003cp\u003eThe T cell receptor (TCR) is a heterodimer composed of either α and β or γ and δ chains. CD3 chains and the CD4 or CD8 co-receptors are also required for efficient signal transduction through the TCR. The TCR is expressed on T helper and T cytotoxic cells that can be distinguished by their expression of CD4 and CD8. T helper cells express CD4 proteins and T cytotoxic cells display CD8. CD8 (also designated Leu 2 or T8), a cell surface glycoprotein, is a two chain complex (αα or αβ) receptor that binds class I MHC molecules presented by the antigen-presenting cell (APC). A primary function of CD8 is to facilitate antigen recognition by the TCR and to strengthen the avidity of the TCR-antigen interactions. An additional role for CD8-expressing T cells may be to maintain low levels of HIV expression.\u003c\/p\u003e","brand":"Bioworld","offers":[{"title":"100ul \/ Rabbit \/ Human","offer_id":47661742457112,"sku":"BS60358-B","price":448.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0590\/5652\/1400\/products\/BIOWORLD_fb6649e3-9c55-48b7-86fa-183e3cd2b61d.jpg?v=1707465777","url":"https:\/\/danabiosci.com\/products\/new-product-224725","provider":"Dana Bioscience","version":"1.0","type":"link"}
