{"product_id":"tnf-af","title":"TNF-α (AF)","description":"\u003cp\u003eTumor Necrosis Factor α (TNF-α) is an inflammatory cytokine secreted by macrophages, monocytes, neutrophils, T cells, and Natural Killer (NK) cells following stimulation by bacterial lipopolysaccharide (LPS). TNF-α signal activation occurs through two receptors, TNFR1 and TNFR2. TNFR1 is expressed on most cell types, unlike TNFR2, which is expressed mainly on immune cells. TNF-α functions to stimulate phagocytosis in macrophages, chemoattract neutrophils, increase insulin resistance, and induce fever.\u003c\/p\u003e","brand":"Cell Guidance Systems","offers":[{"title":"10 μg","offer_id":49304304517376,"sku":"CGS-GFH111AF-10","price":162.89,"currency_code":"NZD","in_stock":true},{"title":"50 μg","offer_id":49304304550144,"sku":"CGS-GFH111AF-50","price":411.51,"currency_code":"NZD","in_stock":true},{"title":"20 μg","offer_id":49304304582912,"sku":"CGS-GFM31AF-20","price":411.51,"currency_code":"NZD","in_stock":true},{"title":"5 μg","offer_id":49304304615680,"sku":"CGS-GFM31AF-5","price":162.89,"currency_code":"NZD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0663\/6591\/5392\/files\/GFH111_1_d49881eb-6ab7-4713-8d1e-e228bd24409a.jpg?v=1787291069","url":"https:\/\/shop.customscience.co.nz\/products\/tnf-af","provider":"Custom Science Ltd","version":"1.0","type":"link"}
