CA 2639196
An immunoassay reagent is provided which comprises an analyte binding agent in a diluent, and a glycosaminoglycan in an amount sufficient to reduce non--specific binding in an assay of a sample for the analyte. Provided is such an immunoassay reagent in which the analyte is troponin I, the analyte binding agent is a biotinylated anti-troponin I antibody, and the glycosaminoglycan is chondroitin sulfate. A sample composition is also provided which comprises a sample to be assayed for the presence of an analyte, an analyte binding agent, and a glycosaminoglycan other than heparin. Further provided is a method of detecting an analyte in a sample, in which non-specific binding is reduced in the method using a glycosaminoglycan.
