{"product_id":"new-product-275155","title":"CD8B polyclonal antibody","description":"\u003cp\u003eThe T cell receptor (TCR) is a heterodimercomposed of either α and β or γ and δ chains. CD3 chains and the CD4 or CD8 co-receptors are also required for efficientsignal transduction through the TCR. The TCR is expressed on T helper and T cytotoxiccellsthatcan be distinguished bytheir expression of CD4 and CD8. T helpercells express CD4 proteins and T cytotoxiccells display CD8. CD8 (also designated Leu 2 or T8), a cellsurface glycoprotein, is a two chain complex(αα or αβ) receptor that bindsclassI MHC molecules presented bythe antigen-presenting cell (APC). A primaryfunction of CD8 is to facilitate antigen recognition bythe TCR and to strengthen the avidity of the TCR-antigen interactions. An additional role for CD8-expressing T cellsmay be tomaintain lowlevels of HIV expression.\u003c\/p\u003e","brand":"ABCbiolab","offers":[{"title":"100ul \/ Rabbit \/ Human,Mouse,Rat","offer_id":45804926697752,"sku":"ABCBW03245","price":325.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0590\/5652\/1400\/products\/758-7580448_monoclonal-antibody-png-transparent-png_1b4e374b-c92b-4c58-8979-f11440571dfe.png?v=1689739327","url":"https:\/\/danabiosci.com\/products\/new-product-275155","provider":"Dana Bioscience","version":"1.0","type":"link"}
