生物活性

产品描述	Apolipoprotein E/APOE2 Protein, Human, Recombinant (His) is expressed in HEK293 Cells. The accession number is P02649-1.
生物活性	Activity has not been tested. It is theoretically active, but we cannot guarantee it.
研究背景	Apolipoprotein E (apoE) is a lipid carrier in both the peripheral and the central nervous systems. Lipid-loaded apoE lipoprotein particles bind to several cell surface receptors to support membrane homeostasis and injury repair in the brain. Considering prevalence and relative risk magnitude, the ε4 allele of the APOE gene is the strongest genetic risk factor for late-onset Alzheimer's disease (AD).
种属	Human
表达系统	HEK293 Cells
标签	C-His
蛋白编号	P02649-1
蛋白构建	Lys19-His317 (R176C)
蛋白纯度	> 95% as determined by Bis-Tris PAGE; > 95% as determined by HPLC
缓冲液	Lyophilized from 0.22 μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.
复溶方法	Reconstitute the lyophilized protein in distilled water. The product concentration should not be less than 100 μg/ml. Before opening, centrifuge the tube to collect powder at the bottom. After adding the reconstitution buffer, avoid vortexing or pipetting for mixing.
内毒素	< 1 EU/μg of the protein as determined by the LAL method.

化学信息

分子量	35.28 kDa (Predicted); 35-42 kDa (Reducing condition, due to glycosylation)

储存&溶解度

运输方式

In general, lyophilized powders are shipped with blue ice, while solutions are shipped with dry ice.

存储

It is recommended to store recombinant proteins at -20°C to -80°C for future use. Lyophilized powders can be stably stored for over 12 months, while liquid products can be stored for 6-12 months at -80°C. For reconstituted protein solutions, the solution can be stored at -20°C to -80°C for at least 3 months. Please avoid multiple freeze-thaw cycles and store products in aliquots.
