Lamivudine triphosphate (3TCTP) TEA is a phosphorylated Lamivudine (a nucleoside analogue). Lamivudine triphosphate TEA inhibits the reverse transcriptase of HIV or HBV viruses to block viral replication by chain termination. Lamivudine triphosphate TEA is also an inhibitor of the RdRp activity of the NS5B subunit of the HCV. Lamivudine triphosphate TEA can be incorporated into the nascent RNA by the SARS-CoV-2 RdRp, thus halting mutations in the nascent SARS-CoV-2 RNA.

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.
