Patent number: 5593826Abstract: Method and kits are provided for detecting one or more target nucleic acids. A first oligonucleotide having a 3' amino group and a second oligonucleotide having a 5' phosphate group are annealed to a contiguous complementary region of a target nucleic acid. Whenever the 3' terminal nucleotides of the first oligonucleotide and the 5' nucleotides of the second oligonucleotide are complementary to the opposing nucleotides on the target nucleic acid, a nucleic acid ligase ligates the first and second oligonucleotides via the formation of a phosphoramidate linkage. The presence of the target nucleic acid is determined by detection of the ligated first and second oligonucleotides.Type: GrantFiled: April 16, 1993Date of Patent: January 14, 1997Assignee: Perkin-Elmer Corporation, Applied Biosystems, Inc.Inventors: Steven Fung, Sergei M.

Patent number: 5521065Abstract: A method of testing for the presence or absence of a target sequence in a mixture of single-stranded nucleic acid fragments is disclosed. The method involves reacting a mixture of single-stranded nucleic acid fragments with a first probe which is complementary to a first region of the target sequence, and with a second probe which is complementary to a second region of the target sequence, where the first and second target regions are contiguous with one another, under hybridization conditions in which the two probes become stably hybridized to their associated target regions. Following hybridization, any of the first and second probes hybridized to contiguous first and second target regions are ligated, and the sample is tested for the presence of expected probe ligation product. The presence of ligated product indicates that the target sequence is present in the sample.Type: GrantFiled: June 8, 1994Date of Patent: May 28, 1996Assignee: Applied Biosystems, Inc.Inventors: Norman M.

Patent number: 5514543Abstract: Method and composition for detecting one or more selected polynucleotide regions in a target polynucleotide. In one embodiment of the invention, a plurality of different-sequence probe pairs are added to a target polynucleotide, where each probe pair includes two polynucleotide probe elements which are complementary in sequence to adjacent portions of a selected one of the target sequences in the target polynucleotide. In each probe pair, one of the probe elements contains a non-polynucleotide polymer chain which imparts a distinctive mobility to the associated probe pair, when the elements in the pair are ligated. The other element in the pair contains a detectable reporter label. After the probe pairs have been allowed to hybridize with the target polynucleotide, the hybridized polynucleotides are treated under conditions effective to ligate the end subunits of target-bound probe elements when their end subunits are base-paired with adjacent target bases.Type: GrantFiled: August 4, 1993Date of Patent: May 7, 1996Assignee: Applied Biosystems, Inc.Inventors: Paul D.
