MAdCAM1 蛋白, Mouse (HEK293, His)

MAdCAM1 is expressed in mucosal venules and serves as a key cell adhesion leukocyte receptor that guides the influx of lymphocytes into mucosal tissues. It regulates leukocyte passage and retention, effectively binding to integrins α-4/β-7 and L-selectin to achieve comprehensive leukocyte adhesion control. MAdCAM1 Protein, Mouse (HEK293, His) is the recombinant mouse-derived MAdCAM1 protein, expressed by HEK293 , with C-His labeled tag.

MAdCAM1 蛋白由粘膜小静脉表达，作为细胞粘附白细胞受体，对于引导淋巴细胞进入粘膜组织（包括派尔集结和肠固有层）至关重要。这种蛋白质在调节白细胞的通过和保留方面发挥着关键作用。MAdCAM1 可有效结合整合素 α-4/β-7 和 L-选择素，有助于全面控制白细胞粘附。MAdCAM1 的亚型 1 和亚型 2 均表现出粘附整合素 α-4/β-7 的能力。值得注意的是，异构体 2 因其缺乏粘蛋白样结构域而著称，可能专门支持整合素 α-4/β-7 依赖性粘附强化，独立于 L-选择素结合。该蛋白质形成同二聚体以实现其介导细胞粘附的功能作用。

60-70 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 from date of receipt. 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.
