研究方向
CHST15(基因位于 10q22.1)是一种高尔基体定位的磺基转移酶,特异性催化硫酸基团向软骨素(Chondroitin)链的转移,形成E单元(Chondroitin sulfate-E, CS-E)。该修饰在细胞外基质重塑、炎症反应及肿瘤转移中发挥关键作用(。CHST15通过调控硫酸软骨素蛋白聚糖(CSPGs)的功能,影响组织纤维化、神经再生及免疫微环境调控。
CHST15作为硫酸化修饰的关键酶,未来需突破:

描述:
Recombinant Human Human CHST15 Protein is produced by 293F expression system. The target protein is expressed with sequence (Ser99-Thr561) of Human Human CHST15 (Accession Q7LFX5) fused with a N-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。
