Abstract
Methods for quantifying the amount of drug present in a crosslinked hyaluronic acid-linker-peptide (xHA-L-P) prodrug composition are provided. Disclosed are steps of contacting a sample of the xHA-L-P prodrug formulation with a hyaluronoglucosidase to generate oligomeric hyaluronic acid-linker-peptide drug (oHA-L-P), contacting the oHA-L-P with a second enzyme to generate peptide digest products of the drug, and detecting the peptide digest products to determine the amount of the drug present in the xHA-L-P prodrug formulation.
