Affymetrix scientists invented the world''s first high-density microarray and began selling the first commercial microarray. Since then, Affymetrix GeneChip technology has become the industry standard in molecular biology research. Affymetrix technology is used by the world''s top pharmaceutical, diagnostic and biotechnology companies as well as leading academic, government and not-for-profit research institutes. Affymetrix'' patented photolithographic manufacturing process provides the most information capacity available today on an array, enabling researchers to use a whole-genome approach to analyzing the relationship between genetics and health.
