Mineral binding peptides with enhanced binding stability in serum

Abstract

Although calcium phosphate (CaP) binding peptides are used to link orthobiologics to orthopedic biomaterials, their binding stability in physiological environment is still unknown. In this study, we investigate the binding capability of a series of CaP-binding peptides and their binding stability in serum solutions, which are selected to resemble physiological conditions. The findings in this study may be applicable for designing robust orthobiologic delivery systems.
