描述
Recombinant Human CD6 Protein is produced by HEK293cells expression system. The target protein is expressed with sequence (His18-Glu398) of human CD6 (Accession #NP_006716.3) fused with an Fc, 6×His tag at the C-terminus.
标签
C-hFc&His
纯度
> 92% by SDS-PAGE.
内毒素
< 0.1 EU/μg of the protein by LAL method.
生物活性
1.Measured by its binding ability in a functional ELISA. Immobilized Human CD166 at 1 μg/mL (100 μL/well) can bind Human CD6 with a linear range of 4-389 ng/mL.
2.Measured by the ability of the immobilized protein to support the adhesion of Jurkat human acute T cell leukemia cells. When 8×104 cells/well are added to CD6 coated plates (5 μg/mL and 100 μL/well) in the ppresence of 10μg/ml PHA, approximately 60-70% cells will adhere specifically after 60 minutes at 37℃.

制剂
Lyophilized from a 0.22 μm filtered solution of PBS, pH 7.4.Contact us for customized product form or formulation.
储存
Store the lyophilized protein at -20°C to -80 °C for long term.
After reconstitution, the protein solution is stable at -20 °C for 3 months, at 2-8 °C for up to 1 week.未开盖的干粉蛋白在 -20°C至-80°C可保存12个月；
复溶之后，蛋白溶液在-20°C及以下可保存3个月，在2-8℃可保存1周。

复溶
Centrifuge the vial before opening. Reconstitute to a concentration of 0.1-0.5 mg/mL in sterile distilled water. Avoid votex or vigorously pipetting the protein. For long term storage, it is recommended to add a carrier protein or stablizer (e.g. 0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose), and aliquot the reconstituted protein solution to minimize free-thaw cycles.收到重组蛋白产品之后请检查蛋白冻干粉末是否贴于瓶底，如果粉末浮起，开盖之前请先低温离心。将蛋白用说明书中指定的缓冲液复溶至0.1-0.5 mg/mL（请注意蛋白复溶浓度不能低于0.1 mg/mL），室温平衡5-10 min保证充分溶解，复溶过程中请不要剧烈涡旋及吹打蛋白溶液。如需长期储存，建议复溶时添加载体蛋白或者稳定剂（如0.1% BSA, 5% HSA, 10% FBS 或者 5% 海藻糖），同时将复溶后的蛋白溶液按照需求进行分装，储存于-20°C至-80°C，随取随用，避免反复冻融。
