Abstract
A method of detecting a protease in a sample. The method comprises providing an analyte degradable by the protease. The analyte is contacted with the sample. The degradation products of the analyte or the residual undegraded analyte is detected in a binding assay.
Claims8
A method of detecting a protease in a sample comprising the steps of:
- (i) providing an unlabelled protein analyte degradable by the protease;
- (ii) contacting the analyte with the sample;
- (iii) contacting the analyte with a specific labelling component such that the labelling component specifically binds to the analyte, wherein the labelling component is associated with a label;
- (iv) capturing the analyte with a specific capture component such that, if intact, the analyte acts as a link between the labelling component and the capture component;
- and
- (v) detecting the presence of the label associated with the capture component, wherein the absence of a detectable label or detection of a reduced label intensity at the location at which the capture component is immobilised is indicative of the presence of a protease in the sample.
