Abstract [en]

A new adenosine nucleotide analog suitable for the Pyrosequencing method is presented. The new analog, 7-deaza-2'-deoxyadenosine-5'-triphosphate (c(7)dATP), has virtually the. same low substrate specificity for luciferase as the currently used analog, 2'-deoxyadenosine-5'-O-(1-thiotriphosphate) (dATPalphaS). The inhibitory effect dATPalphaS displays on the nucleotide degrading activity of apyrase was reduced significantly by substituting the c(7)dATP for the dATPalphaS. Both analogs show high stability after long time storage at +8degreesC. Furthermore, with the new nucleotide a read length of up to 100 bases was obtained for several templates from fungi, bacteria and viruses.
