Related Product Information for Thrombin, APC Substrate protein
Substrates containing the fluorescent reporter group 6-amino-1-naphthalene-sulfonamide (ANSN) are useful compounds for monitoring the enzyme activity of various serine proteases (1-12). In this class of compounds, the ANSN reporter group is linked (in the R1 position) to short tri-peptide sequences. The peptide sequences are designed to optimize the interaction between the enzyme and substrate. Additional components which may be added to the R2 and R3 positions reflect changes in the P' subsite positions, and generally affect the kinetic parameters of the substrates. Compounds which are effective substrates are hydrolyzed between the tri-peptide and the ANSN group. Once cleaved from the peptide moiety, the ANSN group exhibits about a 1000 fold increase in relative fluorescence.
The kinetic properties listed below will aid in the selection of an appropriate substrate. The ANSN substrates have proved especially useful for the analyses of factor VIIa (1-5,7,9,10,12). Although the substrate hydrolysis rates are relatively slow for factor VIIa alone, several compounds exhibit a large change in kcat when tissue factor is incorporated into the assay system.

Product Notes
The Thrombin, APC Substrate (Catalog #AAA635098) is a Protein and is intended for research purposes only. The product is available for immediate purchase. It is sometimes possible for the material contained within the vial of "Thrombin, APC Substrate, Protein" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.Precautions
