Oligonucleotides are immobilized by spotting on a solid support, such as a glass slide. They are hybridized with labeled nucleic acids from a sample and the signals measured, which reflects the composition of the sample nucleic acids. This is performed to either quantify gene expression or genomic profiling to understand genetic variation in humans.
