Proteome Sciences PLC and Researchers at the Institute of Psychiatry Develops Two Novel Proteomic Biomarker Assays For Alzheimer's Disease
Published: Jul 13, 2010
The assays are being presented at the 2010 International Conference on Alzheimer's disease (ICAD) being held this week in Honolulu, Hawaii.
The first presentation describes a mass spectrometer assay for the absolute quantitation of nine blood proteins shown to have utility in the early diagnosis, prediction of disease progression and response to treatment. The proteins include known risk factors for AD such as ApoE and clusterin as well as newly discovered markers such as gelsolin, alpha-2-macroglobulin and complement factor H. The levels of clusterin in blood have recently been shown to be associated with rate of AD progression and to correlate with the diagnostic changes seen with sophisticated imaging equipment. Proteome Sciences has developed a mass spectrometry assay for clusterin available through PS Biomarker Services. The current format of the test uses a tiny amount of blood and takes around 24 hours.
In the second presentation a new method for the routine determination of levels of phosphorylation on a protein called tau is described. Tau is a major component of the characteristic tangles seen in the brains of patients with AD and is thought to contribute to the death of brain cells in a number of neurodegenerative diseases as a result of hyperphosphorylation. The method can measure subtle changes in the levels of phosphorylation in tau and will initially be used to evaluate the potential of new treatments to prevent the pathological phosphorylations of tau. In addition to developing the tau screening assay, a number of protein kinases were also confirmed as significant targets in the tau hyperphosphorylation pathway.
The two assay methods will be available from Proteome Sciences’ ISO 9001:2008 accredited Frankfurt facility and can be outsourced through PS Biomarker Services.
