Abstract
The present invention relates to a method and reagents for determining the presence of or the amount of an analyte in a sample.
Claims27
A method for determining the presence of or the amount of an analyte in a sample comprising:
- (i) providing a sample suspected of containing an analyte;
- (ii) contacting the sample with a fluorescent tracer and a binding partner to provide an assay composition;
- wherein the binding partner is specific for the analyte and the fluorescent tracer;
- (iii) irradiating the assay composition with light at a first wavelength;
- and
- (iv) measuring the intensity of light emitted at a second wavelength,
- wherein the intensity of the light emitted at the second wavelength is proportional to the concentration of the analyte in the sample.
