A DNA microarray assay measures the expression of thousands of genes simultaneously by hybridizing labeled cDNA samples to DNA fragments fixed on a glass slide.
DNA microarray assays are used to simultaneously measure the expression levels of thousands of genes by hybridizing labeled cDNA samples to single-stranded DNA fragments fixed on a glass slide.
