IL-13 蛋白, Mouse (CHO, His)

IL-13 Protein, Mouse (CHO, His), an important CHO cell derived cytokine, is a multifunctional cytokine whose principal action is to diminish inflammatory responses.

白细胞介素(IL)-13在过敏性哮喘的发病机制中发挥着关键作用。在动物模型中，被动施用其单克隆抗体或可溶性受体来阻断过量产生的IL-13已被证明可以有效控制气道过敏反应，但这些方法存在半衰期短、成本高和可能产生不良反应的缺点。IL-13诱导Ca²⁺激活氯通道的基因表达，刺激上皮细胞分化，促进粘蛋白基因表达和释放。IL-13 在哮喘发病机制中发挥着关键作用^[1]。

14-30 kDa

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

无菌粉末.

Lyophilized after extensive dialysis against PBS.

<0.2 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.
