Deoxynucleoside 5'-triphosphates 100 mM solution, 4x25
Spectral characteristics of dNTPs
Deoxynucleoside 5'-triphosphates are chemically synthesized from deoxynucleoside 5'-monophosphate and purified by Ion-Exchange and reverse phase chromatography (purity > 98%).
dNTPs effectively direct PCR with the amplicon size up to 10 kb. Each particular dNTP is free from any traces of other dNTPs. dNTPs are supplied in sodium salts, in solutions and in powder. Applications of dNTPs include PCR, long PCR, Real Time PCR, RT-PCR, cDNA synthesis, primer extension, DNA sequencing and labeling.
Recently a very high sensitivity of Pfu DNA polymerase to traces of pyrophosphate has been discovered. It is quite difficult to find traces of pyrophosphates in dNTPs, so dNTPs from some commercial sources can cause problems in PCR with Pfu DNA Polymerase.
All dNTP batches from Sibgene are carefully tested for effective PCR both with Taq DNA Polymerase and Pfu DNA Polymerase. Moreover, the products are tested for the absence of other inorganic salts.
dNTPs provided by Sibgene are RNase free - a very sensitive fluorescent test for RNase activity provided by Ambion can not detect traces of RNase in the preparations.
