Product Description	Recombinant Human IL-18BP Protein is expressed from HEK293 with hFc 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.
Product Category	Recombinant Protein / Antibody discovery

Protein	IL-18BP
Synonyms	IL-18BP; Igifbp
Accession	O95998-2
Species	Human
Biotinylated	no
Amino Acid Range	Thr31-Gly194
Molecular Weight	The protein has a predicted MW of 44.4 kDa. Due to glycosylation, the protein migrates to 60-80 kDa based on Bis-Tris PAGE result.

Purity	> 95% as determined by Bis-Tris PAGE
Endotoxin	Less than 1EU per ug by the LAL method.

Form	Lyophilized
Shipping	Shipped at ambient temperature.
Formulation	Lyophilized from 0.22um filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.
Reconstitution	Centrifuge the tube before opening. Reconstituting to a concentration more than 100 ug/ml is recommended. Dissolve the lyophilized protein in distilled water.
Stability And Storage	-20 to -80°C for 12 months as supplied from date of receipt.；-80°C for 3 months after reconstitution.；Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.
