Background: TFPI

Human 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 a N-terminal acidic region, three Kunitz (K) domains separated with by two linker regions, and a C-terminal basic region (2). The first K domain (residues 54 to 104) inhibits coagulation factor VIIa complexed to tissue factor (TF). The second K domain (residues 125 to 175) inhibits factor Xa. The third K domain (residues 217 to 267) binds to heparin (3). The C-terminal basic region may have several functions. For example, it plays an important role in binding of TFPI to cell surfaces (2).

FAQs for Human TFPI Antibody

Showing  1 - 1 的 1 FAQ Showing All

    • Q: Do the TFPI antibodies (Catalog #s MAB2974, MAB29741, and BAF2974) detect TFPI-alpha or TFPI-beta?
      A: These antibodies were raised against Asp29-Lys282 of isoform 1 of Accession # P10646. Isoform 1 is also known as TFPI-alpha. We do not epitope map our antibodies, so we do not know where within Asp29-Lys282 these antibodies bind. Since TFPI-alpha and TFPI-beta share 100% homology from aa1-209, it is possible that our antibodies recognize both the alpha and beta forms of TFPI.
