研究方向
CREG1（Cellular Repressor of E1A-Stimulated Genes 1）是一种在细胞分化、增殖和凋亡中起重要作用的蛋白质。它在多种生物过程中发挥调控作用，尤其在心血管系统、肿瘤和免疫系统中具有重要意义。以下是关于CREG1的关键信息：
生物活性
Measured by its binding ability in a functional ELISA. When rhIGF-II R is immobilized at 2 μg/mL (100 µL/well), the concentration of rhCREG that produces 50% of the optimal binding response is found to be approximately 2- 10 ng/mL.

>95% by SDS-PAGE.
内毒素：
＜0.1EU/ug of the protein by LAL method.
制剂：
Lyophilized from a 0.22 μm filtered solution of PBS, pH 7.4.Contact us for customized product form or formulation.
描述：
Recombinant Human Human CREG1/CREG Protein is produced by 293F expression system. The target protein is expressed with sequence (Met1-Gln220) of Human Human CREG1/CREG (Accession O75629) fused with a C-His.
储存：
Store at -20℃.Store the lyophilized protein at -20℃ to -80 ℃ up to 1 year from the date of receipt.
After reconstitution, the protein solution is stable at -20℃ for 3 months, at 2-8℃ 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 vortex 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。
