研究方向
Human Pentraxin 2/SAP 是由 APCS 基因编码的 五聚体模式识别蛋白，属于短链五聚蛋白家族，主要由肝脏合成并分泌至血液。其核心功能包括：
生物活性
Measured by its binding ability in a functional ELISA. When Recombinant Human Fc gamma RllA/CD32a (R167) is immobilized at 2 µg/mL (100 µL/well), the concentration of Recombinant Human Pentraxin 2/SAP that produces 50% of the optimal binding response is 0.175-1 μg/mL.

描述：
Recombinant Human Human Pentraxin 2/SAP Protein is produced by 293F expression system. The target protein is expressed with sequence (His20-Val223) of Human Human Pentraxin 2/SAP (Accession P02743) fused with a C- 10*His tag.
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。
