| 20120003744 | DIAGNOSTIC METHODS - The present invention provides a method for identifying a biomarker for diagnosis of lymphoma in a canine subject. The method comprises the following steps: (i) providing serum samples from canine subjects with lymphoma (lymphoma samples); (ii) providing serum samples from canine subjects free from lymphoma (control samples); (iii) fractionating the protein components in the serum samples provided in steps (i) and (ii) using anion exchange chromatography; (iv) further purifying proteins from the fractionated samples produced in step (iii) by contacting the proteins therein with a SELDI protein chip comprising a cation exchange surface; (v) characterising the proteins adhered to the cation exchange surface of the SELDI protein chip in step (iv) using mass spectrometry; and (vi) performing a classification and regression tree (CART) analysis to identify proteins capable of acting as biomarkers, either alone or in combination with other proteins. The invention further provides biomarkers for use in the diagnosis of canine lymphoma and methods of diagnosis using the same. | 01-05-2012 |
