研究方向
IDS(基因位于 Xq28)是溶酶体磺酸酯酶家族关键成员。通过催化硫酸乙酰肝素(HS)和硫酸皮肤素(DS)中艾杜糖醛酸-2-硫酸酯的水解,参与糖胺聚糖(GAGs)代谢,其缺陷导致黏多糖贮积症II型(亨特综合征)。酶替代疗法(ERT)和基因治疗为其主要干预手段。

描述:
Recombinant Human Human Iduronate 2
sulfatase/SIDS Protein is produced by 293F expression system. The target protein is expressed with sequence (Ser26-Pro550) of Human Human Iduronate 2
sulfatase/SIDS (Accession P22304) fused with a C-

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。
