Tissue factor pathway inhibitor (TFPI) serves as a critical regulator of the extrinsic coagulation cascade, making it a key target in cardiovascular and thrombosis research. This recombinant human TFPI (aa 29–282, C-terminal 10×His tag) demonstrates confirmed binding activity in functional ELISA, where immobilized protein at 1 μg/mL engages an anti-TFPI recombinant antibody with an EC50 of 1.242–1.788 ng/mL—providing a reliable positive control for antibody screening, epitope mapping, and sandwich ELISA development. Mammalian cell expression preserves native-like post-translational modifications essential for proper Kunitz domain folding and ligand recognition. Purity exceeding 95% by SDS-PAGE combined with endotoxin levels below 1.0 EU/μg satisfies the criteria typical for both cell-based functional assays investigating coagulation inhibition and protein–protein interaction studies exploring TFPI engagement with Factor Xa or tissue factor/Factor VIIa complexes.
Applications : Western Blot
Review: We used the 35 kDa protein TFPI (CUSABIO, Wuhan, China) added with the His-tag as the control Subsequently, we detected the purified recombinant proteins by Western blot with anti-His and found that Chi2 and Chi14 were 44 KD and 37 KD, respectively.
