Abstract

Flavin adenine dinucleotide-labeled conjugates of the formula: ##STR1## wherein Riboflavin--Phos).sub.2 Ribose represents the riboflavin-pyrophosphate-ribose residue in flavin adenine dinucleotide (FAD), --NH)L is a protein or polypeptide (e.g., an immunoglobulin) bound through an amino group thereof, n is an integer from 2 through 10, m is an integer from 1 through 10, and p is on the average from 1 to the number of available amino groups in L. The FAD-labeled conjugates are useful as reagents in specific binding assays (e.g., immunoassays) to determine the conjugated protein or polypeptide, or a specific binding analog or partner thereof, in liquid media.
