分子别名(Synonym)
Coagulation Factor III, Tissue Factor, TF, F3, CD142
表达区间及表达系统(Source)
Human Tissue Factor, His Tag (TF3-H52H5) is expressed from human 293 cells (HEK293). It contains AA Ser 33 - Glu 251 (Accession # P13726-1).
Predicted N-terminus: Ser 33
蛋白结构(Molecular Characterization)

This protein carries a polyhistidine tag at the C-terminus.
The protein has a calculated MW of 26.7 kDa. The protein migrates as 35-45 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
内毒素(Endotoxin)
Less than 1.0 EU per μg by the LAL method / rFC method.
纯度(Purity)
>90% as determined by SDS-PAGE.
>95% as determined by SEC-MALS.
制剂(Formulation)
Lyophilized from 0.22 μm filtered solution in 50 mM Tris, 150 mM NaCl, pH7.5 with trehalose as protectant.

背景介绍
全长组织因子(TF)是一种跨膜受体,同时也是凝血因子VII/FVIIa的辅因子。除全长TF外,还可通过可变剪接产生缺失跨膜结构域的可溶性TF变体(asTF),该变体可被细胞释放。与TF不同,由于缺乏跨膜结构域,asTF仅具有较低的促凝血活性。组织因子由血管周围细胞(如外膜成纤维细胞)和体表细胞(如上皮细胞)表达,在止血过程中起关键作用,同时也参与多种血栓形成过程。许多癌症(尤其是腺癌)会高表达TF,而肿瘤组织因子高表达与乳腺癌、前列腺癌、结直肠癌和胰腺癌等多种癌症的不良预后相关。
