Arrayit Technology Purchased by Johns Hopkins University to Study Rheumatoid Arthritis

Medical Center Uses Arrayit Protein Microarray Platform to Identify Biomarkers for Autoimmune Diseases

SUNNYVALE, CA--(Marketwire - November 18, 2009) - Arrayit Corporation (OTCBB: ARYC) announced today that the new High Throughput Biology Center at Johns Hopkins University School of Medicine in Baltimore Maryland purchased Arrayit's proprietary technology to create a Human Proteome Chip to discover biomarkers for autoimmune diseases including rheumatoid arthritis, inflammatory bowel disease, autoimmune hepatitis (first identified by Dr. Zhu), lupus, and others.

Arrayit's patented NanoPrint microarray platform deposits nanoliter quantities of proteins onto glass substrates to create the chips. Johns Hopkins, which strongly endorses the Arrayit Platform and NanoPrint robot, is also considering Arrayit's consumable stream of substrates and reagents.

"Because of the high capacity of the NanoPrint, we use it to print 17,000 human proteins on a single glass slide. You can see all 17,000 proteins for their auto-immunity, covering 80% of the human proteome," said Dr. Heng Zhu, Assistant Professor at Johns Hopkins. "We call that The Human Proteome Chip."

Arrayit NanoPrint platforms have been installed at other major research and diagnostics centers including Harvard University in Massachusetts, Sandia National Laboratories in New Mexico, Scripps Research Institute in Florida, The Biodesign Institute in Arizona, and Mount Sinai School of Medicine in New York City.
