Overview

application：

Thymidine 5′-triphosphate (dTTP) is one of the four natural deoxynucleotides, along with deoxyadenosine 5′-triphosphate (dATP), deoxyguanosine 5′-triphosphate (dGTP) and deoxycytosine 5′-triphosphate (dCTP) used for the biosynthesis of deoxyribonucleic acids by DNA polymerases and reverse transcriptases. Deoxy-TTP may also be used as a substrate to study the specificity and kinetics of thymidine-triphosphatase(s) (EC 3.6.1.39) and other dTTP hydrolyzing activities.

Note

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. Refer to SDS for further information. Need more advice on solubility, usage and handling? Please visit our frequently asked questions (FAQ) page for more details.
