Product Description	Recombinant Biotinylated Human IL-18BP Protein is expressed from HEK293 with His tag and Avi tag at the C-Terminus.It contains Thr31-Gly194.
Product Background	Cytokines were the first modern immunotherapies to produce durable responses in patients with advanced cancer,components of the interleukin-18 (IL-18) pathway are upregulated on tumour-infiltrating lymphocytes, suggesting that IL-18 therapy could enhance anti-tumour immunity. IL-18BP, a high-affinity IL-18 decoy receptor, is frequently upregulated in diverse human and mouse tumours and limits the anti-tumour activity of IL-18 in mice.
