Abstract
Methods for determining the presence of large molecular weight aqueous ligands. The sample ligands are made to compete with user supplied fluorescently labeled peptides for binding sites on a ligand binding partner. Presence of aqueous ligand and binding of ligand binding partner thereto leaves the fluorescently labeled peptides free to exhibit fluorescence depolorization effects.
