TFPI2 human

NA.32

Tissue Factor Pathway Inhibitor 2 (TFPI­2), also known as placental protein 5 (PP5) and retinal pigment epithelial cell factor 1 (REF­1), is a member of the Kunitz-type serine proteinase inhibitor family, is a structural homologue of tissue factor pathway inhibitor (TFPI). TFPI2 is highly abundant in the full-term placenta and widely expressed in umbilical vein endothelial cells, liver, placenta, heart, pancreas, and maternal serum at advanced pregnancy. TFPI­2 may play a role in the regulation of plasmin-mediated matrix remodeling. Inhibits trypsin, plasmin, factor VIIa/tissue factor and weakly factor Xa and has no effect on thrombin. Reduced synthesis of TFPI-2 has been related to numerous pathophysiological processes such as inflammation, angiogenesis, atherosclerosis, retinal degeneration and tumor growth / metastasis.

Lyophilized from 0.22 μm filtered solution in 20 mM MES and 100 mM NaCl, pH 6.5. Normally Mannitol or Trehalose is added as protectants before lyophilization.

Centrifuge the vial prior to opening. Reconstitute in sterile PBS, pH 7.4 to a concentration of 50 μg/mL. Do not vortex. This solution can be stored at 2-8℃ for up to 1 month. For extended storage, it is recommended to store at -20℃.
