dTTP, PCR Grade, is suitable for many applications where high-quality reagents are required. Such procedures include reverse transcription (RT), polymerase chain reaction (PCR), RT-PCR, DNA labeling reactions, and sequencing/cycle sequencing analysis.

General description

PCR Grade nucleotides from Roche are specially manufactured and purified to the highest possible chemical purity. PCR Grade nucleotides contain at least 99% of the relevant deoxynucleoside-triphosphate (dNTP) and less than 0.9% deoxynucleoside-diphosphate (dNDP).

Thymidine 5′-triphosphate sodium salt solution is used in DNA synthesis reactions such as PCR, DNA sequencing, cDNA synthesis and molecular cloning techniques.

dTTP, PCR Grade, is a 100 mM clear, colorless solution of the sodium salt (pH 8.3).

Other Notes

For general laboratory use.

Preparation Note

Working solution: We recommend to prepare a deoxynucleotide mix containing dATP, dCTP, dGTP, dTTP (10 mM, each); (e.g., for the preparation of 100 μl nucleotide mix add 10 μl of dATP, dCTP, dGTP, dTTP (each) to 60 μl Water, PCR Grade).


Function tested in RT-PCR. Tested for absence of contaminating deoxyribonucleases, ribonucleases and nicking activities according to the current Quality Control procedures.

Physical form

solution of dTTP in water (pH 8.3).
