History

Affymetrix, Inc. was spun-off from Affymax Research Institute by Alex Zaffaroni in 1993, and was eventually based in Santa Clara, California, United States. It began as a unit in Affymax N.V. in 1991 under Fodor and his group. In the late 1980s, that group had developed methods for fabricating DNA microarrays, under the "GeneChip" Affymetrix trademark, using semiconductor manufacturing techniques. The company's first product, an HIV genotyping GeneChip, was introduced in 1994 and the company went public in 1996.

, Affymetrix's GeneChip arrays assisted researchers in quickly scanning for the presence of particular genes in a biological sample. In this area, Affymetrix was focused on oligonucleotide microarrays, which could be used to address the presence of genes through detection of specific corresponding segments of mRNA. The single-use chips could be used to analyze thousands of genes in a single assay. The company also manufactured machinery for high speed analysis of biological samples, and its GeneChip Operating Software as a system for managing Affymetrix microarray data. Affymetix's competitors in the DNA Microarray business include Illumina, GE Healthcare, Applied Biosystems, Beckman Coulter, Eppendorf Biochip Systems, and Agilent.


Acquisitions

Prior to its acquisition by Thermo Fisher, and its becoming a line of its products, Affymetrix, Inc. had acquired the technologies of a number of companies. It acquired Genetic MicroSystems for slide-based microarrays and scanners and Neomorphic for

FDA test approval

In January 2014, the Food and Drug Administration cleared a first-of-a-kind whole-genome postnatal blood test that can aid physicians in identifying the underlying genetic cause of developmental delay, intellectual disability, congenital anomalies, or dysmorphic features in children, where it was noted that " out 2 to 3 percent of U.S. children have some sort of intellectual disability, according to the National Institutes of Health." The test, known as CytoScan Dx Assay, was designed to diagnose these disabilities earlier to expedite appropriate care and support.
