Fluorescently labeled molecules derived from the transcripts of two tissue samples are hybridized to immobilized DNA molecules on the surface of an array. Thus, spots on the micoarray that are more green than red represent genes that are more abundant in the tissue sample from which green-labeled molecules were derived. (Original-Deyholos-CC:AN)
