蛋白结构(Molecular Characterization)

Online(Asp 29 - Lys 282) NP_006278.1

This protein carries a polyhistidine tag at the C-terminus.

The protein has a calculated MW of 30.0 kDa. The protein migrates as 41-45 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

标记(Biotinylation)

The primary amines in the side chains of lysine residues and the N-terminus of the protein are conjugated with biotins using standard chemical labeling method. A standard biotin reagent (13.5 angstroms) is used in this product.

蛋白标记度(Biotin:Protein Ratio)

Passed as determined by the HABA assay / binding ELISA.

内毒素(Endotoxin)

Less than 1.0 EU per μg by the LAL method.

纯度(Purity)

>95% as determined by SDS-PAGE.

制剂(Formulation)

Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally trehalose is added as protectant before lyophilization.

电泳(SDS-PAGE)

Biotinylated Human TFPI, His Tag, primary amine labeling (Cat. No. TFI-H8226) SDS-PAGE gel

Biotinylated Human TFPI, His Tag, primary amine labeling on SDS-PAGE under reducing (R) condition. The gel was stained overnight with Coomassie Blue. The purity of the protein is greater than 95%.

背景(Background)

Tissue factor pathway inhibitor (TFPI) is also known as Extrinsic pathway inhibitor (EPI), Lipoprotein - associated coagulation inhibitor (LACI), is a plasma proteinase inhibitor synthesized by vascular endothelial cells and part of it is associated with glycosaminoglycans of these cells. TFPI is a single-chain polypeptide which can reversibly inhibit Factor Xa (Xa) and Thrombin (Factor IIa). TFPI is a secreted protein with a N­terminal acidic region, three Kunitz (K) domains separated with by two linker regions, and a C­terminal basic region. The first K domain inhibits coagulation factor VIIa complexed to tissue factor (TF); The second K domain inhibits factor Xa; The third K domain binds to heparin; The C­terminal basic region may have several functions. For example, it plays an important role in binding of TFPI to cell surfaces.
