Abstract
The application refers to a method for detecting and quantifying multiple target analytes in a test sample using a single reaction vessel. The method uses a reaction vessel (a multi-well plate), which comprises a microarray of: (a) calibration spots, each having a predetermined quantity of the target analyte; and (b) capture spots, each having an agent (antibody) that selectively binds the target analyte. The captured analytes and the calibration spots are detected with fluorescently labelled antibodies specific for each different target analyte. The calibration spots are used to generate calibration curves that allow the measurement of the concentration of the different target analytes. The application also refers to a method for detecting and quantifying biomarkers that are useful for diagnosing rheumatoid arthritis. More specifically, the application discloses the use of rheumatoid factor (RF) and cyclic citrullinated peptide (CCP), as capture spots. Finally, based on the above method, it is proposed a method for diagnosing or monitoring rheumatoid arthritis.
