表達區(qū)間及表達系統(tǒng)(Source)
Human IL-18BP, His Tag (ILP-H5222) is expressed from human 293 cells (HEK293). It contains AA Thr 31 - Gly 194 (Accession # NP_001138529).
Predicted N-terminus: Thr 31
蛋白結構(Molecular Characterization)

This protein carries a polyhistidine tag at the C-terminus.
The protein has a calculated MW of 18.5 kDa. The protein migrates as 35-45 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.
內(nèi)毒素(Endotoxin)
Less than 1.0 EU per μg by the LAL method / rFC method.
純度(Purity)
>90% as determined by SDS-PAGE.
>90% as determined by SEC-MALS.
制劑(Formulation)
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 with trehalose as protectant.

背景介紹
白細胞介素18結合蛋白(IL18BP)亦稱為Tadekinig-alfa、IL18BPa,其功能為IL18抑制劑。該蛋白是一種分泌型蛋白,包含一個免疫球蛋白樣C2型結構域。由于缺乏跨膜結構域,IL18BP不會錨定在細胞膜上。其在心臟、肺、胎盤和脾臟中呈現(xiàn)高表達。IL18BP的A亞型可與IL-18結合并抑制其活性,還能作為早期TH1細胞因子反應的抑制劑。該蛋白通過抑制γ干擾素(IFN-γ)的產(chǎn)生,進而削弱1型輔助T細胞(Th1)的免疫應答。
