| 产品描述：Interleukin-18 binding protein (IL-18BP) is a constitutively secreted glycoprotein that acts as a natural antagonist for interleukin-18 (IL-18) by preventing interaction between IL-18 and its receptors. Through this binding, IL-18BP neutralizes the proinflammatory role of IL-18 in cell-mediated immune responses, resulting in reduced IFN-γ production by T helper type I cells and inhibition of allospecific cytotoxic T lymphocyte (CTL) activity through augmented natural killer (NK) cell cytotoxicity. As an inhibitor of IL-18 and an essential component of skin homeostasis, IL-18BP has been linked to a variety of diseases, including eczema, asthma, and the autoimmune condition, Crohn’s disease. The upregulation of IL-18BP by keratinocytes expressing the human papillomavirus (HPV) E7 oncoprotein has been shown to decrease IL-18-induced IFN-γ production and IL-18-mediated T cell activation. Elevated levels of IL-18 and IL-18BP, as well as proinflammatory cytokines IFN-γ, TNF-α, IL-1β and IL-8, have been linked to chronic inflammation and observed in macrophages (including Kupffer cells) isolated from lesions and intestinal tissues of Crohn’s disease patients. As a member of the immunoglobulin-like class of receptors, IL-18BP contains a single immunoglobulin (Ig) domain; although two (b and d) of the four identified human isoforms (a-d) contain incomplete domains that greatly reduce their binding affinity. PeproTech’s CHO cell-derived Recombinant Human IL-18BP Fc is a glycosylated, disulfide-linked homodimer of 792 amino-acid-residues whose monomer consists of a 163-amino-acid portion of secreted IL-18BP fused to the 231-amino-acid length Fc portion of human IgG by two glycine residues. The calculated molecular weight of monomeric CHO cell-derived Recombinant Human IL-18BP Fc is 43.6 kDa; however, due to glycosylation, it migrates at an apparent molecular weight of approximately 60-65 kDa by SDS-PAGE analysis under reducing conditions.来源:CHO cells别名:Interleukin-18-binding protein, IL-18BPa, Tadekinig-alfa氨基酸序列 (monomer):TPVSQTTTAA TASVRSTKDP CPSQPPVFPA AKQCPALEVT WPEVEVPLNG TLSLSCVACS RFPNFSILYW LGNGSFIEHL PGRLWEGSTS RERGSTGTQL CKALVLEQLT PALHSTNFSC VLVDPEQVVQ RHVVLAQLWA GLRATLPPTQ EALPSSHSSP QQQGGPKSCD KTHTCPPCPA PELLGGPSVF LFPPKPKDTL MISRTPEVTC VVVDVSHEDP EVKFNWYVDG VEVHNAKTKP REEQYNSTYR VVSVLTVLHQ DWLNGKEYKC KVSNKALPAP IEKTISKAKG QPREPQVYTL PPSRDELTKN QVSLTCLVKG FYPSDIAVEW ESNGQPENNY KTTPPVLDSD GSFFLYSKLT VDKSRWQQGN VFSCSVMHEA LHNHYTQKSL SLSPGK纯度:≥ 95% by SDS-PAGE gel and HPLC analyses.生物活性:Determined by its ability to neutralize IL-18 induced IFN-γ production in KG-1 cells.Calculated Molecular Weight:87.2 kDaAccession Number:O95998Gene ID:10068原产地:USA仅用于科研，不能用于临床和诊断。 |
