Description:A HCV protease substrate that incoporates an ester bond between residues P1 and P1. Due to ready transesterification of the scissile bond to the acyl-enzyme intermediate, this substrate shows very high kcat/Km values, enabling detection of activity with subnanomolar nonstructural protein 3 (NS3 protease) concentrations. It is widely used for the continuous assay of NS3 protease activity. Substrate cleavage is proportional to the enzyme concentration with a detection limit for NS3 between 1 nM and 250 pM. Upon cleavage of this substrate, fluorescence can be monitored at Abs/Em = 355/500 nm. As an internally quenced fluorogenic substrate, it can be used to monitor HCV NS3 protease activity.

After receiving:
The packaging of the product may have turned upside down during transportation, resulting in the natural compounds adhering to the neck or cap of the vial. take the vial out of its packaging and gently shake to let the compounds fall to the bottom of the vial. for liquid products, centrifuge at 200-500 RPM to gather the liquid at the bottom of the vial. try to avoid loss or contamination during handling.
Note:
1. It is recommended that the concentration of the stock solution be around 1-2 mg of peptide per ml of solution. This is dilute enough to minimize the potential precipitation of the peptides during storage, but concentrated enough to take relatively small volumes (< 100 µl) of aliquots for the assay, and therefore minimizing the effect of the solvents initially used for solubilization.

2. Stability of peptides have no uniform standards. The stability of each peptide depends on its sequence information. We suggest Lyophilized peptides should be stored at -20 °C. It is recommended that peptides containing methionine, cysteine, or tryptophan residues be stored in oxygen-free atmosphere to avoid oxidation.
