组织因子 (TF) 通过与循环因子 VII 或 VIIa 形成复合物,成为血液凝固的重要引发剂。所得的[TF:VIIa]复合物促进因子IX或X的特定有限蛋白水解,从而通过启动细胞表面组装和凝血蛋白酶级联的传播在正常止血中发挥关键作用。

研究方向
TF(基因位于 小鼠3号染色体,又称 F3或 CD142)是凝血系统核心起始因子。由血管内皮细胞、巨噬细胞及肿瘤细胞表达,通过激活凝血级联和细胞信号转导,在血栓形成、炎症及肿瘤微环境中发挥双重作用(促凝/非凝血信号),是血栓性疾病和癌症治疗的研究靶点。
生物活性
Measured by its ability to activate Coagulation Factor VII in cleaving a fluorogenic peptide substrate Boc-VPR-AMC. The AC50 is <5 µg/mL, as measured under the described conditions

标签:
C-His
纯度:
>95% by SDS-PAGE.
内毒素:
<0.1EU/ug of the protein by LAL method.
制剂:
Lyophilized from a 0.22 μm filtered solution of PBS, pH 7.4.Contact us for customized product form or formulation.
描述:
Recombinant Mouse Mouse Tissue Factor Protein is produced by 293F expression system. The target protein is expressed with sequence (Ala29-Glu251) of Mouse Mouse Tissue Factor (Accession P20352) 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。
