Abstract
A tyrosine-substituted hirudin analog has antithrombogenic activity. Further simultaneous reaction at native tyrosine residues is prevented by mutation at those sites to encode nonreactive amino acids. Several novel strategies for coupling the hirudin analog to solid surfaces while simultaneously conserving antithrombogenic activity are disclosed.
