3′-Azido-2′,3′-dideoxy-CTP (AZddCTP) is a cytidine analog containing a 3-azido group. As a chain terminator, 3′-Azido-2′,3′-dideoxy-CTP can be incorporated into the nascent DNA chain by HIV reverse transcriptase. 3′-Azido-2′,3′-dideoxy-CTP terminates DNA synthesis due to the lack of a 3'-hydroxyl group, thereby inhibiting viral replication. 3′-Azido-2′,3′-dideoxy-CTP has IC50 values of 15.6 μM and 160.8 μM for WT HIV and AZTR HIV. 3′-Azido-2′,3′-dideoxy-CTP has antiviral activity.

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.
