Name : Human TFPI-2 Protein
Product Source :
Recombinant Human TFPI-2 Protein is expressed from HEK293 with His tag at the C-Terminus. It contains Asp23-Lys213.[Accession | NP_006519.1]
Molecular Weight :
The protein has a predicted MW of 22.9 kDa. Due to glycosylation, the protein migrates to 30-35 kDa based on Tris-Bis PAGE result.
Endotoxin Level :
Less than 1EU per μg by the LAL method.
Purity :
> 95% as determined by Tris-Bis PAGE
Formulation :
Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.
Reconstitution :
Centrifuge the tube before opening. Reconstituting to a concentration more than 100 μg/ml is recommended. Dissolve the lyophilized protein in distilled water.
Storage and Stability :
-20 to -80°C for 12 months as supplied from date of receipt. -80°C for 3-6 months after reconstitution. 2-8°C for 2-7 days after reconstitution. Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.
Product Concentration :
Tris-Bis PAGE Human TFPI-2 on Tris-Bis PAGE under reduced condition. The purity is greater than 95%. Bioactivity Data Measured by its ability to inhibit trypsin cleavage of a fluorogenic peptide substrate, the IC50 value is
Background :
Tissue factor pathway inhibitor-2 (TFPI-2) has previously been characterized as an endogenous anticoagulant. TFPI-2 is expressed in the vast majority of cells, mainly secreted into the extracellular matrix. Moreover, in sputum from cystic fibrosis patients TFPI-2 C-terminal fragments are generated and found associated with immunoglobulins. Together our data describe a previously unknown host defense mechanism and therapeutic importance of TFPI-2 against invading Gram-negative bacterial pathogens.
Synonyms :
TFPI-2; PP5; TFPI2; REF1; TFPI-2REF1
