There is very little known about many of the triphosphates we sell. Please see our table of Enzymatic Activity of Selective NTPs, or our NTP bibliography in our website and catalog to see if there is a publication regarding your question. If not, our stock answer is often tongue in cheek: buy the compound, be the first to do the research, publish the paper and then we will both know. Seriously, we are attempting through both in-house and collaborative efforts to learn more about potential applications of our compounds, but this is a long term effort. Please contact us to see if there is any news about your particular application.
