  Sodium azide is recommended to avoid contamination (final concentration 0.05%-0.1%). It is toxic to cells and should be disposed of properly. Avoid repeated freeze-thaw cycles.

TFPI Antibody Background

Tissue factor pathway inhibitor (TFPI) is a Kunitz-type serine proteinase inhibitor that down-regulates tissue factor-initiated blood coagulation. TFPI is synthesized by vascular endothelial cells and part of it is associated with glycosaminoglycans of these cells. In plasma TFPI exists as both a free-form (active) and an associated with lipoprotein form (nonactive). TFPI inhibits t Inhibits factor X (X(a)) directly and, in a Xa-dependent way, inhibits VIIa/tissue factor activity, presumably by forming a quaternary Xa/LACI/VIIa/TF complex. TFPI contains 3 BPTI/Kunitz inhibitor domains, The first domain interacts with VIIa and TF, the second one with Xa. Decreasing TFPI activity facilitates an activation of blood coagulation and fibrin forming, and may also be a beneficial therapeutic agent to attenuate pathologic clotting. The mouse TFPI isoform alpha is expressed in heart and spleen while isoform beta is in heart and lung.
