研究方向
IGFBP2(基因位于 2q33-q34)是胰岛素样生长因子结合蛋白家族的重要成员(截至2025年4月9日最新研究)。其通过调控IGF信号通路、独立受体相互作用及表观遗传修饰,在胚胎发育、代谢稳态和肿瘤微环境中发挥多效性功能,是代谢性疾病和癌症治疗的潜在靶点。
生物活性
Immobilized Recombinant Human IGFBP-2 at 5 μg/mL (100 μL/well) can bind Recombinant Human IGF1 with a linear range of 50-220 ng/mL.

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 IGFBP2 Protein is produced by 293F expression system. The target protein is expressed with sequence (Glu40-Gln328) of Human Human IGFBP2 (Accession P18065) 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。
