Patent ID: 6929944

Claim:
A method for detecting a target biopolymer in a sample, comprising: (a) preparing a microarray of said sample by dispensing aliquots of said sample at discrete sites onto a substrate and immobilizing said target biopolymer on said substrate, wherein the microarray is an array of dots, each dot having a diameter from about 1 to 500 microns, wherein each of said aliquots contains the same amount of said target biopolymer; (b) contacting said microarray with one or a plurality of probe biopolymers under conditions that allow the formation of one or a plurality of complexes, each complex comprising said target biopolymer and one of said probe biopolymers, wherein said probe biopolymers are dispensed on said dots in said microarray; and (c) detecting the presence of and quantifying said complexes as a measurement for the presence or the amount of the target biopolymer in said sample.
