If the exact amino acid sequence of this recombinant protein is critical to your application,
please explicitly request the full and complete sequence of this protein before ordering.
Tag Info
C-terminal 10xHis-tagged
The tag type will be determined during production process. If you have specified tag type, please tell us and we will develop the specified tag preferentially.
Buffer
Lyophilized from a 0.2 μm filtered 20 mM Tris-HCl, 0.5 M NaCl, 6% Trehalose, pH 8
Storage
Store at -20°C/-80°C upon receipt, aliquoting is necessary for mutiple use. Avoid repeated freeze-thaw cycles.
Lead Time
3-7 business days
Note: All of our proteins are default shipped with normal blue ice packs, if you request to ship with dry ice, please communicate with us in advance and extra fees will be charged.
Notes
Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.
Shelf Life
The shelf life is related to many factors, storage state, storage temperature and the stability of the product itself. Generally, the shelf life of lyophilized form is 6 months at -20°C/-80°C from the date of receipt.

Description
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.
