背景

白细胞介素-4（IL-4）又称IL-13，是一种分泌蛋白，属于IL-4/IL-13家族。IL-4/IL-13具有多种生物学作用，包括刺激活化的B细胞和T细胞增殖。在IL-4和IL-13（Th-2型免疫反应中产生的细胞因子，尤其是在过敏和寄生虫感染期间）存在下，巨噬细胞会被差异性激活，而IL-4和IL-13是白细胞介素-4受体的配体。

预测分子量

15.4 kDa

实际分子量

17-20 kDa, reducing conditions

纯度

>95% as determined by Bis-Tris PAGE.

内毒素

< 0.1 EU/ug by the LAL method

制剂

Lyophilized from 0.22μm filtered solution in PBS with BSA as a carrier protein. Normally 8% trehalose is added as protectant before lyophilization.

复溶方法

开盖前先10,000-12,000 rpm 离心 30 s；向冻干粉中加入无菌PBS，用枪头轻轻吹打混匀，重悬浓度不低于 100 μg/mL；复溶之后分装放-80℃保存，避免反复冻融。

储存条件 (自收到货起)

For long-term storage, keep the product lyophilized at -20°C or below. Please avoid repeated freeze-thaw cycles. Stability: Lyophilized: 12 months (-20°C to -80°C) Reconstituted: 3 months at -80°C under sterile conditions

Data

: Recombinant Rat IL-4 Protein (HEK293)on SDS-PAGE under reducing (R) and non-reducing (NR) conditions. The gel was stained with Coomassie Blue. The purity of the protein is greater than 95%.
