Protein microarray is probably the only technique currently available for systematic investigation of protein-protein interactions. This protocol describes an optimized method to probe yeast protein microarrays for protein-protein interactions using purified V5-epitope tagged fusion protein. It should also apply to any other proteins with appropriate modifications.
