IL-18BP 蛋白, Human (HEK293, hFc)

IL-18BP Protein belongs to immunoglobulin superfamily that bind to IL-18 and inhibits its activity. IL-18BP Protein functions as an inhibitor of the Th1 cytokine response^[1]. IL-18BP Protein, Human (HEK293, hFc) is the recombinant human-derived IL-18BP protein, expressed by HEK293 , with C-hFc labeled tag. The total length of IL-18BP Protein, Human (HEK293, hFc) is 164 a.a., with molecular weight of 55-80 kDa.

IL-18BP 蛋白是一种细胞因子受体，可抑制 IL-18 与其受体的结合，从而抑制 IL-18 诱导的 IFN-γ 产生，导致 1 型辅助 T 免疫反应降低^[1]。IL-18BP 蛋白在单核细胞中组成型表达和分泌^[2]。在克罗恩病患者的肠道组织中检测到 IL-18BP 蛋白水平升高^[3]。

Greater than 95% as determined by reducing SDS-PAGE or Tris-Bis PAGE.

无菌粉末

Lyophilized from a 0.2 μm filtered solution of PBS, pH 7.4.

<1 EU/μg, determined by LAL method.

It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH₂O. For long term storage it is recommended to add a carrier protein (0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose).

Stored at -20°C for 2 years. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.

Room temperature in continental US; may vary elsewhere.
