Analyte assay using particulate labels
First Claim
1. A method for comparing and identifying nucleic acid sequences in two or more collections of labeled nucleic acids, the method comprising:
- providing a plurality of nucleic acid probes bound to a solid surface, at least some of said plurality comprising a nucleic acid complementary to a nucleic acid sequence in said collections to be compared;
contacting the nucleic acid probes with a first collection of labeled nucleic acids having a first type of label, and at least a second collection of labeled nucleic acids having a second type of label;
wherein said first and second types of labels are light scattering particles and are distinguishable from each other and wherein said labeled nucleic acids in said first and second collections bind to said probes; and
detecting the binding for each of the first and at least second labeled nucleic acids to the nucleic acid probes;
thereby comparing and identifying said nucleic acid sequences in said two or more collections.

Abstract
Method for specific detection of one or more analytes in a sample. The method includes specifically associating any one or more analytes in the sample with a scattered-light detectable particle, illuminating any particle associated with the analytes with light under conditions which produce scattered light from the particle and in which light scattered from one or more particles can be detected by a human eye with less than 500 times magnification and without electronic amplification. The method also includes detecting the light scattered by any such particles under those conditions as a measure of the presence of the analytes.
