Background

TFPI (Tissue factor pathway inhibitor) also known as EPI, LACI, TFI and TFPT1 is a single-chain polypeptide which can reversibly inhibit Factor Xa (Xa) and Thrombin (Factor IIa). While Xa is inhibited, the Xa-TFPI complex can subsequently also inhibit the FVIIa-tissue factor complex. TFPI contributes significantly to the inhibition of Xa in vivo, despite being present at concentrations of only 2.5 nM. The gene for TFPI is located on chromosome 2q31-q32.1, and has nine exons which span 70 kb. TFPI has a relative molecular mass of 34,000 to 40,000 depending on the degree of proteolysis of the C-terminal region.

Immunogen

A synthetic peptide corresponding to a sequence at the N-terminus of human TFPI.

Clonality

Polyclonal

Tissue Specificity

Mostly in endothelial cells.

Applications

IHC,WB

Purification

Immunogen affinity purified.

Concentration

Adding 0.2 ml of distilled water will yield a concentration of 500 μg/ml.

Form

Lyophilized

Reconstitution

Add 0.2ml of distilled water will yield a concentration of 500ug/ml.

Function

Inhibits factor X (X (a)) ly and, in a Xa-dependent way, inhibits VIIa/tissue factor activity, presumably by forming a quaternary Xa/LACI/VIIa/TF complex. It possesses an antithrombotic action and also the ability to associate with lipoproteins in plasma.

Components

Each vial contains 5mg BSA, 0.9mg NaCl, 0.2mg Na2HPO4, 0.05mg Thimerosal, 0.05mg NaN3.
