研究方向
CHI3L2是一种糖基水解酶家族成员(缺乏酶活性),通过结合多糖和细胞表面受体(如IL-13Rα2)调控炎症、组织重塑和肿瘤微环境。在关节炎、纤维化疾病和恶性肿瘤中高表达,是疾病进展的生物标志物和潜在治疗靶点
CHI3L2是连接慢性炎症与恶性转化的"多面手"分子,未来需突破:
生物活性
Measured by the ability of the immobilized protein to support the adhesion of FaDu human squamous cell carcinoma cellsWhen 5 x 10^4 cells per well are added to rhCHI3L2 coated plates for 30 minutes at 37 °C, cell adhesion is enhanced in a dose dependent manner with typical ED50 range of 0.7-2.8 μg/mL. Opitimal dilutions should be determined by each laboratory for each application.

描述:
Recombinant Human Human Chitinase 3-like 2 Protein is produced by 293F expression system. The target protein is expressed with sequence (Tyr27-Leu390) of Human Human Chitinase 3-like 2 (Accession Q15782) 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。
