Immobilization of a bone and cartilage stimulating

A synthetic peptide fragment of human collagen type I (BCSP™-1) was linked to the surface of a commercially available ceramic in an effort to improve the properties of the bone graft substitute to accelerate local healing. BCSP™-1 was covalently immobilized on the surface of the ceramic via the linkers 3-aminopropyl-triethoxysilane (APTES) and suberic acid bis-N-hydroxysuccinimide ester (DSS).

Primary amine buffers such as Tris (TBS) are not compatible, because they compete for reaction. However in some procedures, it is useful to add Tris or glycine buffer at the end of a conjugation procedure to stop the reaction. N ...
