The conditions under which oligonucleotide probes hybridize preferentially with entirely complementary and homologous nucleic acid targets are described. Using these hybridization conditions, overlapping oligonucleotide probes associate with a target nucleic acid. Following washes, positive hybridization...http://www.google.com/patents/US5525464?utm_source=gb-gplus-sharePatent US5525464 - Method of sequencing by hybridization of oligonucleotide probes
