N-1506-100 100 µmole

Ribonucleoside triphosphates (rNTPs) are the building blocks of RNA molecules and are essential to the success of RNA drug development. TriLink’s rNTPs are manufactured under stringent quality standards in an ISO-9001 certified facility, offering exceptional quality, purity, and consistency.  They are ideally suited for RNA synthesis in research, diagnostics, therapeutics, and vaccine development. 

Substituting uridines with modified uridines, such as N1-methylpseudouridine, 5-methoxyuridine, and pseudouridine, can reduce immunogenic response and enhance translational efficiency of mRNAs. These properties can result in safer mRNA and increased protein expression. 

The rNTP set with N1-methylpseudo-UTP contains separate tubes of 100 mM ATP, CTP, GTP, and N1MePs-UTP in H2O, pH 7.5. The rNTPs can be used with TriLink’s patented CleanCap® capping technology in in vitro transcription for robust RNA manufacturing.

Products FAQs

A nucleoside contains only the base and the sugar (5'-OH) while a nucleotide refers to a nucleoside with phosphorylation on the sugar. This includes the phosphate groups on the 2', 3' or 5' ends.

We provide custom chemistry services. Please inquire about the feasibility of your desired nucleotide at

They are resuspended in water, pH 7.5±0.5.

A 1 µmole vial of 100 mM NTP contains 10 µL.

In general, we recommend equimolar amounts of nucleotides in IVT. The exact amounts depend on the IVT reagents and conditions. Please see our rNTP product inserts for IVT with CleanCap M6 and CleanCap AU analogs.

Yes, it can. Our product inserts have recommended ratios for small-scale IVT. If you would like to discuss it further, please contact us at or [email protected].

When stored properly at or below -20°C, NTPs should be stable for a few years. Upon first use, prepare aliquots to minimize freeze-thaw cycles and NTP degradation. 

Although NTPs are stable at room temperature for several days, they are shipped on wet or dry ice to ensure stability in the event of a transportation delay. Even if they have arrived thawed, they should still be good to use. If you have concerns or questions however, please contact us at or [email protected].

Each NTP is accompanied by a certificate of analysis with the methods of analysis, concentration, purity, identity, etc. Our GMP NTPs undergo further analyses for characterization, safety, and nuclease contamination.

We run 31P NMR, which reveals inorganic phosphate salt. Enzymologists usually have the most concern about this salt since it inhibits many polymerases.
