Preparation and Storage

Background: TFPI

Tissue Factor Pathway Inhibitor (TFPI), also known as lipoprotein-associated coagulation inhibitor (LACI) and extrinsic pathway inhibitor (EPI), is a physiological inhibitor of extrinsic pathway of coagulation and has biological functions of anticoagulation and anti-inflammation (1). It is a secreted protein with an N-terminal acidic region, three Kunitz (K) domains separated by two linker regions, and a C-terminal basic region (2). The first K domain (residues 50-100) inhibits coagulation factor VIIa complexed to tissue factor (TF). The second K domain (residues 121-171) inhibits factor Xa. The third K domain (residues 225-275) binds to heparin (3). The C-terminal basic region may have several functions. For example, it plays an important role in the binding of TFPI to cell surfaces (2). The purified recombinant mouse TFPI ends at residue 289 and does not contain the last 17 residues (residues 290-306) in the C-terminal region. It inhibits the activity of recombinant human Coagulation Factor VII (R&D Systems, Catalog # 2338-SE) in the presence of recombinant human Tissue Factor (Catalog # 2339-PA) .
