MIF 蛋白, Human (HEK293, His)

The MIF protein is a pro-inflammatory cytokine that is critical for the innate immune response against bacterial pathogens. Its presence at sites of inflammation suggests a role in modulating macrophage function to promote host defense. MIF counteracts the anti-inflammatory effects of glucocorticoids. Although MIF exhibits tautomerase activity in vitro, its physiological substrates remain unknown, and the relevance of this activity to its cytokine function is unclear. MIF Protein, Human (HEK293, His) is the recombinant human-derived MIF protein, expressed by HEK293, with C-His labeled tag. The total length of MIF Protein, Human (HEK293, His) is 114 a.a., with molecular weight of 25-30 kDa.

MIF 蛋白是一种促炎细胞因子，在针对细菌病原体的先天免疫反应中发挥着至关重要的作用。它在炎症部位的表达表明它参与调节宿主防御中的巨噬细胞功能。MIF 抵消糖皮质激素的抗炎作用。尽管 MIF 在体外具有苯丙酮酸互变异构酶和多巴色素互变异构酶活性，但 MIF 的生理底物仍不清楚。目前尚不清楚互变异构酶活性是否与其细胞因子活性相关。

25-30 kDa

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

无菌粉末

Lyophilized from a 0.22 μm filtered solution of PBS, pH 7.4. Normally 8% trehalose is added as protectant before lyophilization.

<1 EU/μg, determined by LAL method.

It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH₂O.

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.
