Abstract
The present invention relates methods for making stable calibrators and controls that can be used in ligand-binding assays.
Claims15
A method of making a stable liquid calibrator or control for use in a ligand binding assay for measuring a level of a natriuretic peptide in a test sample, wherein the method comprises the steps of:
- a. mixing at least one diluent with at least one human synthetic natriuretic peptide to form a liquid calibrator or control;
- b. measuring a pH of the liquid calibrator or control;
- and
- c. depending upon the pH of the liquid calibrator or control measured in step b), adjusting the pH of the liquid calibrator or control to a pH of from about 4.0 to about 6.5.
