NEW YORK, June 3 - Ciphergen said today that researchers at Health Canada's National Microbiology Lab, the Beijing Clinical SARS Testing Center, and the Genomic Institute of Singapore are using its ProteinChip technology to search for novel protein biomarkers associated with Severe Acute Respiratory Syndrome.
Ciphergen said that "a number of potential biomarkers have already been discovered in SARS patient samples" using the company's Expression Difference Mapping protocols on nasopharyngeal, serum, and other samples.
The biomarkers will be further evaluated for use in developing protein-based diagnostic tests for SARS, the company said in a statement, adding that gene-based approaches to diagnosing SARS "currently show significant false negative results."
Ciphergen also said it has collaborated with Health Canada to identify one of the SARS coronavirus proteins by sequencing parts of the protein and determining the mass of protein fragments on a ProteinChip tandem mass spectrometry interface.
Ciphergen has filed for a US patent on the protein.
