Microarray scanners

Microarray scanners are instruments that read the fluorescent signal from a hybridised microarray slide, converting the intensity at each spot into a quantitative measure of gene expression, genotype, or protein binding. They illuminate the array with one or more laser wavelengths and record the emission through a photomultiplier or CCD detector, producing an image a buyer then analyses with feature-extraction software. On Questpair, 159 used laboratory microarray scanners are listed from 10 verified suppliers and distributors across 5 countries. Among the current listings, 100 percent are used. Prices run from EUR 86 to EUR 64.562, so the catalogue spans both compact single-colour readers and high-throughput scanning platforms sold new for far more.
