TFPI ELISA kits are immunoassay tools for the measurement of the protein tissue factor pathway inhibitor, which is encoded by the TFPI gene in humans. Functionally, this protein is reported to inhibit 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. The canonical protein structure is reported to have an amino acid sequence of 304 residues and a mass of 35 kDa. It is known to be secreted. As many as 2 protein isoforms have been reported. The protein has been noted to be post-translationally O-glycosylated. Other alias names for this target include LACI, TFI, TFPI1, anti-convertin, extrinsic pathway inhibitor, and EPI.
Some TFPI ELISA kits can detect targets at levels as low as 5 pg/mL and as high as 2000 ng/mL. Click on the products below for more detailed ELISA kit information, such as target reactivity and assay sensitivity.
