Protein-dye conjugate for confirmation of correct dilution of calibrators

摘要

The present invention has multiple aspects that include an intermediate composition (i.e., a marked stock calibrator solution) for preparing diluted calibrator solutions that are marked in proportion to the amount of calibrator contained therein; a diluted (i.e., working) calibrator solution made therefrom, a series of diluted calibrator solutions that are visually colored in proportion to the concentration of calibrator therein; a method for performing a diagnostic assay that employs a series of marked calibrator solutions; a method for confirming that a stock solution of calibrator has been diluted correctly; and a method for indirectly confirming the concentration of calibrator in a working calibrator solution.
