3'-O-(2-Nitrobenzyl)-dTTP acts as a reversible terminator for DNA chain elongation. 3'-O-(2-Nitrobenzyl)-dTTP interacts with 9°N polymerase (exo-) A485L/Y409V, gets recognized and incorporated into the elongating DNA chain, thereby temporarily terminating the polymerase reaction. 3'-O-(2-Nitrobenzyl)-dTTP carries a 3'-O-(2-nitrobenzyl) blocking group, which can be removed by laser irradiation to regenerate the free 3'-OH− group and restore polymerase activity. 3'-O-(2-Nitrobenzyl)-dTTP is applicable in DNA sequencing studies.

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.
