生物活性

产品描述	Kallikrein 3/KLK3 Protein, Human, Recombinant (aa 25-261, His) is expressed in HEK293 Cells. The accession number is P07288-1.
生物活性	Immobilized Human Kallikrein 3, His Tag at 0.5 μg/ml (100 μl/well) on the plate. Dose response curve for Anti-Kallikrein 3 Antibody, hFc Tag with the EC50 of 4.0 ng/ml determined by ELISA (QC Test).
研究背景	Kallikrein-related peptidase 3 (KLK3), also known as prostate-specific antigen (PSA), is the most useful biomarker for prostate cancer (PCa). KLK3 is suggested to play a role in regulating cancer growth through anti-angiogenic activity in vivo and in vitro.
种属	Human
表达系统	HEK293 Cells
标签	C-His
蛋白编号	P07288-1
蛋白构建	Ile25-Pro261
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 50 mM Tris, 150 mM NaCl, 0.05% Brij-35 (pH 7.5). 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.
别名	PSA, KLK2A1, kallikrein related peptidase 3, Hk3, APS
内毒素	< 0.1 EU/μg of the protein as determined by the LAL method.

化学信息

分子量	27.7 kDa (Predicted); 31-38 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.
