Tessarae Will Use Affy Arrays to Develop Pathogen-Detection Kit

NEW YORK (GenomeWeb News) — Affymetrix today said Tessarae, a maker of tests to identify infectious diseases, will use its microarrays to develop and market new epidemiological research tests for public health surveillance.  
Under the terms of the agreement, Tessarae has non-exclusive rights to Affy’s CustomSeq resequencing arrays to develop kits that will recognize viral and bacterial pathogens based on genotypic signatures.
Affy said the arrays have been tailored to detect upper respiratory pathogens from target sequences provided by the US Naval Research Laboratory. The tests will be designed for common pathogens such as those causing respiratory disease and pneumonia, as well as respiratory biothreat agents.
Tessarae’s PCR-based kits will be used by public health officials to identify pathogens during an outbreak. Affy said the TessArray RPM-Flu3.0 kits will allow physicians to simultaneously detect particular strains, substrains, and nucleotide changes.
Financial terms of the agreement were not released.
Tessarae started this program with a $35-million infusion from US Department of Defense. The company patented the platform in November 2006.
Tessarae plans to develop test kits for encephalitis, hemorrhagic fever, and other blood-borne infections.
