Microarray and uses therefor
First Claim
1. A kit comprising:
- at least one antibody array, said antibody array comprising a plurality of discrete locations arrayed in a spatially addressable ordered matrix on a solid surface, wherein each of the discrete locations comprises one or more spots of an antibody bound to the solid surface, wherein a plurality of the discrete locations contain antibodies that are different from the antibodies of the other discrete locations;
a first detectable label for labeling a first protein sample;
optionally a second detectable label for detectably labeling a second protein sample, wherein the second detectable label is different from the first detectable label; and
instructions for using the kit to perform one or more of the following;
i. identifying antigens in the first or the second protein samples that bind to one or more of the antibodies bound to the solid surface;
ii. comparing the protein expression profiles of two or more protein samples;
iii. characterizing the first or the second protein samples based on the protein expression profile thereof; and
iv. determining the effect of varying binding conditions on the affinity of the bound antibodies to antigens present in first or second protein samples.

Abstract
The invention disclosed herein comprises methods of using microarrays to simplify analysis and characterization of genes and their function. In one aspect of the invention the methods are used to identify and characterize antibodies having binding affinity for a specific target antigen. The invention further comprises a method of determining gene expression at the protein level comprising contacting an array of characterized or uncharacterized antibodies on a solid surface with one or more proteins and identifying the antibodies to which said protein(s) binds. This method can be additionally used to compare the protein expression in two different populations of cells, such as normal cells and cancer cells or resting cells and stimulated cells. A further aspect of the invention comprises a method of determining gene expression at the protein level comprising contacting a microarray of nucleic acid samples derived from a variety of different sources with one or more nucleic acid probes then identifying the sample or samples to which the probe binds.
