Self-assembling protein microarrays arrays can be used to study protein-protein interactions, protein-drug interactions, search for enzyme substrates, and as tools to search for disease biomarkers.  In particular, recent experiments have focused on using these protein microarrays to search for autoantibody responses in cancer patients.  These experiments show promise in finding antibody responses that appear in only cancer patients.  New methods using click chemistry-based reagents also allow the application of these arrays for discovering new substrates of post translational modification.
