3′-Deoxy CTP is a nucleotide analogue and a mandatory chain terminator. 3′-Deoxy CTP can cause chain termination by lacking the 3′-hydroxyl group, inhibiting the RNA synthesis activity of HCV nonstructural protein (NS5B) polymerase and blocking viral replication. 3′-Deoxy CTP can be used to study the chain termination mechanism of HCV polymerase and the development of antiviral drugs.

Providing storage is as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to 24 months.
Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20°C. Generally, these will be useable for up to one month. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.
