Abstract
Conjugates are provided which are covalently bonded conjugates of an anticoagulant and protein that are prepared in the presence of a coupling agent that forms amide linkages between the anticoagulant and the protein. Such amide linking coupling agents exclude highly toxic coupling agents such as CNBr. These conjugates are useful for enhancing the blood compatibility of certain surfaces of a prosthetic device, a surgical apparatus, or an extra-corporeal medical device.
Claims2
An article including a surface having an enhanced blood compatibility coating, wherein the coating is effected from a conjugate of anticoagulant and a water soluble protein, said protein being a non-crosslinked protein or a crosslinked protein, said conjugate having been formed by coupling a protein component and an anticoagulant with an amide bond forming agent.
