20110312529 | CONFORMATIONAL PROBES AND METHODS FOR SEQUENCING NUCLEIC ACIDS - This disclosure provides a method of determining a sequence of nucleotides for a nucleic acid template. The method can include the steps of contacting the nucleic acid template with a conformationally labeled polymerase and at least four different nucleotide species under conditions wherein the conformationally labeled polymerase catalyzes sequential addition of the nucleotide species to form a nucleic acid complement of the nucleic acid template, wherein the sequential addition of each different nucleotide species produces a conformational signal change from the conformationally labeled polymerase and wherein the rate or time duration for the conformational signal change is distinguishable for each different nucleotide species; detecting a series of changes in the signal from the conformationally labeled polymerase under the conditions; and determining the rates or time durations for the changes in the signal, thereby determining the sequence of nucleotides for the nucleic acid template. | 12-22-2011 |
