TFPI2
Background
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.

Biological activity
Measured by its ability to inhibit trypsin cleavage of a fluorogenic peptide substrate, Mca - RPKPVE - Nval - WRK (Dnp) - NH2. The IC50 value is < 2.5 nM, as measured in 100μL reaction mixture containing 1.25 ng trypsin, 10 μM substrate, 50 mM Tris, 10 mM CaCl2, 0.15 M NaCl, 0.05% Brij-35, pH 7.5.

Physical properties
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.
How to reconstitute
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°C for up to 1 month. For extended storage, it is recommended to store at -20°C.

Properties
Human proteins, cDNA and human recombinants are used in human reactive ELISA kits and to produce anti-human mono and polyclonal antibodies. Modern humans (Homo sapiens, primarily ssp. Homo sapiens sapiens). Depending on the epitopes used human ELISA kits can be cross reactive to many other species. Mainly analyzed are human serum, plasma, urine, saliva, human cell culture supernatants and biological samples.
