Abstract
The invention provides novel reagents and methodologies for detecting free versus bound compounds. It is particularly useful to detect thrombin when it is not bound to A2M in the presence of thrombin bound to A2M by using a modified substrate that is sterically hindered from reacting with the bound thrombin.
Claims2
A modified peptide substrate that is modified by attaching a macromolecule via a spacer that comprises 9-15 atoms, wherein the modified peptide substrate is cleavable by a free proteinase but not by a proteinase bound in a molecular trap, and wherein the peptide substrate is S2238, and the proteinase is thrombin.
