Protein and antibody profiling using small molecule microarrays
First Claim
1. A method of profiling a plurality of distinct ligand binding moiety in a sample comprising:
- (a) providing an array of ligands having a plurality of random structures;
(b) contacting said array with a biological sample comprising ligand binding moiety; and
(c) assessing binding of ligand binding moiety to said array, wherein binding of ligand binding moiety to said array detects ligand binding moieties in said sample.

Abstract
Aspects of the present invention describe methodology by which arrays of synthetic molecules can be created and employed for various types of proteomics profiling experiments. The most important of these from a clinical standpoint are the visualization of antibody and T cell binding patterns, which could be employed as a tool for monitoring the state of the immune system of a patient. This may be a generally useful tool for the diagnosis of many types of disease states. Similar techniques are employed to detect the post-translational modification of specific proteins, a tool for the visualization of induction of signal transduction pathways in cells and tissues treated with drugs. Finally, aspects of the invention teache a method for the creation of simpler arrays with less than 100 features that are, nonetheless, effective for protein profiling experiments.
