Abstract
The present invention provides methods and apparatus for sequencing, fingerprinting and mapping biological macromolecules, typically biological polymers. The methods make use of a plurality of sequence specific recognition reagents which can also be used for classification of biological samples, and to characterize their sources.
Claims4
A method of using a fluorescent label to detect hybridization with polynucleotide probes of known sequence, said method comprising:
- (a) attaching said label to a target polynucleotide,
- (b) contacting under hybridization conditions said labeled target polynucleotide sequence with a collection of polynucleotide probes of known sequences wherein said probes are attached to a substrate at known locations;
- and
- (c) determining the sequences of the probes which hybridize with said target, said collection comprising at least 100 different probes per square centimeter of substrate.
A method of mapping a plurality of polynucleotide sequences relative to one another, said method comprising:
- (a) preparing a substrate having attached thereto at known locations a plurality of sequence specific probes comprising at least about 100 probes per square centimeter of substrate;
- (b) subjecting each of said polynucleotide sequences to contact with the probes attached to said substrate under hybridization conditions;
- and
- (c) determining the relative locations of said hybridizations on said sequences to determine the overlaps and order of said plurality of polynucleotide sequences.
A method comprising the steps of:
- (a) hybridizing non-identical oligonucleotide probes attached to a substrate at a density of at least 100 of said probes per square centimeter with target DNA;
- (b) identifying a first oligonucleotide probe which hybridizes in step (a) with said target DNA;
- (c) further identifying other oligonucleotide probes which hybridize in step (a) beginning with a second oligonucleotide probe;
- and
- (d) continuing said identification to identify at least about 100 probes which hybridize with said target DNA.
