Patent ID: 8710015

Claim:
A method for forming an implant having a pre-defined glycosaminoglycan (GAG) binding activity comprising: (a) selecting tropoelastin monomers; (b) forming a composition with the selected monomers; and (c) cross linking the monomers in the composition in the presence of a mould for forming an implant wherein an implant having GAG binding activity is formed when a tropoelastin monomer containing tropoelastin domain 26A is selected, thereby forming an implant having a pre-defined glycosaminoglycan (GAG) binding activity and wherein the implant comprises a tropoelastin selected from the group consisting of SHELδmodified (SEQ ID NO: 5), SHELgamma (SEQ ID NO: 9), SHEL31-36 (SEQ ID NO: 10), SHEL32-36 (SEQ ID NO: 11 and SHELδ26A SEQ ID NO: 3).
