ANGPTL8/Angiopoietin-like 8 蛋白, Human (HEK293, Fc)

ANGPTL 8 Protein, Human (HEK293, Fc) is a secreted inhibitor of LPL. Angiopoietin-like Protein 8 may function as an important metabolic switch, by forming complexes with ANGPTL3, or with ANGPTL4, in order to direct the flow of energy from triglycerides in blood according to the needs of the body.

血管生成素样蛋白 (ANGPTL) 是一个由八种分泌糖蛋白组成的家族，它们与血管生成素表现出结构同源性，并具有不同的生理功能，包括在脂质代谢、干细胞扩增、炎症、组织重塑和血管生成中的假定作用。近年来，三种ANGPTL，ANGPTL3、ANGPTL4和ANGP-TL8，已被证明在脂质代谢和血脂水平调节中发挥作用。ANGPTL4 和 ANGPTL8 重新折叠在一起时形成复合物，并且该复合物中的 ANGPTL4 失去灭活 LPL 的能力。我们观察到 ANGPTL8 的 C 端螺旋对于与 ANGPTL3 或 ANGPTL4 形成复合物非常重要，而不是像之前提出的那样覆盖蛋白质的功能位点。

Approximately 54.0 kDa

Greater than 90% as determined by reducing SDS-PAGE.

无菌粉末.

Lyophilized after extensive dialysis against 20 mM PB, 150 mM NaCl, pH 7.4 or 20 mM Tris-HCl, 10% Trehalose, 0.05% Tween 80, pH 8.0.

<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.
