Flavin adenine dinucleotide-labeled protein and polypeptide conjugates.

摘要

Flavin adenine dinucleotide-labeled conjugates of the formula:
wherein Riboflavin (Phos) 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., immuoassays) to determine the conjugated protein or polypeptide, or a specific binding analog or partner thereof, in the liquid media.
