Abstract
Engineered nucleotide compositions, having polymerase interacting components that improve the interactivity of the polymerase and the nucleotide, particularly for nucleic acid sequencing applications. Compositions include the interactive polymerases along with the nucleotide analogs. Kits, methods and systems are provided for analysis of nucleic acid synthesis reactions.
Claims9
A method of monitoring polymerase mediated, template dependent primer extension, comprising:
- providing a polymerase template primer complex;
- contacting the complex with a nucleotide composition, comprising the structure:
- N—Y—F
- wherein N is a nucleoside polyphosphate or analog thereof;
- F is a detectable label moiety;
- and
- Y comprises a polymerase interacting linkage complex comprising a polymerase interacting group positioned from 20 to 40 angstroms from a nucleoside portion of the nucleoside polyphosphate;
- and
- monitoring reaction of the nucleotide composition with the complex in a primer extension reaction by detecting a signal from the detectable label.
