Nonclinical pharmacodynamics, pharmacokinetics and safety profiles of anti-human transferrin receptor antibody-fused Nsulfoglucosamine sulfohydrolase for mucopolysaccharidosis type IIIA

We present a protein immobilization system, based on the Src Homology 3 (SH3) affinity domain, allowing for a transient interaction between a fibronectin ligand and a biomaterial surface. This strategy leads to enhanced retention of the fibronectin fragment over adsorbed fibronectin, and increased cellular proliferation and motility over either covalently immobilized or adsorbed fibronectin. The results indicate that intermediate affinity protein immobilization could provide benefits for tissue engineering beyond the traditional immobilization techniques, adsorption or covalent attachment.
