It is a key component of the CD8 receptor complex, which is predominantly found on cytotoxic T lymphocytes (CTLs). CD8α can form either an α\/β heterodimer with CD8β or an α\/α homodimer, both of which play essential roles in CTL activation and function. By interacting with the TCR (T cell receptor) and MHC I molecules, CD8α helps recruit the LCK kinase, initiating multiple signaling pathways that drive the CTL-mediated immune response.\u003cbr\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003eThis product is a F(ab) fragment derived from the anti-mouse CD8α antibody clone 2.43. Unlike full-length antibodies, this F(ab) fragment contains only the antigen-binding region and lacks the Fc domain, allowing specific binding to CD8α while eliminating Fc-mediated effects such as complement activation and Fcγ receptor engagement.\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003eThis Fc-free format is suitable for studies requiring CD8α targeting without inducing immune effector functions, antibody cross-linking, or CD8⁺ T cell depletion. It can also be applied in targeted delivery strategies, such as nanoparticle-based systems for selective CD8⁺ T cell targeting and in vivo delivery of genetic payloads.\u003cbr\u003e\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Starter","offers":[{"title":"1mg","offer_id":43083768791115,"sku":"S0B7035-1mg","price":666.67,"currency_code":"USD","in_stock":true},{"title":"5mg","offer_id":43083768823883,"sku":"S0B7035-5mg","price":2500.0,"currency_code":"USD","in_stock":true},{"title":"25mg","offer_id":43083768856651,"sku":"S0B7035-25mg","price":8333.33,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0590\/8375\/1499\/files\/AntBioImage_a57f07b4-82a0-4238-bd58-dfc87c480c35.png?v=1787943720","url":"https:\/\/www.antbioinc.com\/products\/invivo-anti-mouse-cd8-recombinant-mab-fab2-fragment-s0b7035","provider":"AntBio","version":"1.0","type":"link"}
