jHemo PC® Phosphorylcholine Hemocompatible Coating

jHemo PC® phosphorylcholine hemocompatible coating is hydrophilic, biocompatible, and resistant to protein, cellular and microbial adhesion. Performance tests of the coating demonstrated that, compared to uncoated devices, thrombosis weight is reduced by 90% and clotting time is increased by 50%. The coatings can be used in a variety of cardiovascular and neurovascular medical devices.

jHemo PC® Phosphorylcholine Hemocompatible Coating

Product Introduction

The main component of the coating is phosphorylcholine (PC). PC is the main lipid on the outer layer of the non-activated cell membrane, which is an amphiphilic (hydrophilic and lipophilic) phospholipid, that resists protein and cell adhesion.

PC is covalently bonded to the surface of the devices, it can reduce the thrombosis caused by protein aggregation and serves as an anti-clotting agent. Material containing PC is surrounded by water molecules, and these water molecule layers effectively cover the substrate to which it is applied, providing a biological "non-stick" surface that resists protein and cell adhesion, and acts as an anti-adhesive and anti-crystallization agent.
