摘要:
The invention provides a family of nucleotide analogs useful in sequencing nucleic acids containing a homopolymer region comprising, for example, two or more base repeats, and to sequencing methods using such nucleotide analogs.
摘要:
In one aspect the invention relates to an apparatus for analyzing the presence of a single molecule using total internal reflection. In one embodiment an apparatus for single molecule analysis includes a support having a sample located thereon; two sources of light at distinct wavelengths, a collimator for directing the light onto the sample through a total internal reflection objective; a receiver for receiving a fluorescent emission produced by a single molecule in the sample in response to the light; and a detector for detecting each of the wavelengths in the fluorescent emission. In another embodiment the apparatus further comprises a focusing laser for maintaining focus of the objective on the sample.

摘要:
Methods of the invention comprise methods for nucleic acid sequence determination. Generally, the invention relates to sequencing a target nucleic acid by exposing the target nucleic acid to a primer and a polymerase. Such methods may involve determining the sequence of a target nucleic acid by using a thermophilic polymerase, such as a variant of said 9° N DNA polymerase.
摘要:
The invention provides methods for correcting misincorporation of a nucleotide in a primer during a sequencing-by-synthesis reaction by using both a polymerase substantially lacking in exonuclease activity and an enzyme, preferably a polymerase, having exonuclease activity.
