Suitable for almost all Octet^® SPR assays, the Octet^® SPR CDH sensor chip is comprised of a 3D carboxymethylated dextran matrix sensor chip surface. Molecules of interest can be covalently bound to the surface using a range of different amine, aldehyde, thiol or carboxyl functional chemical groups. The Octet_® SPR CDH sensor chip is one of the most widely used Octet^® SPR sensor chips due to its versatility and high binding capacity, making it suitable for many diverse applications from small fragment research to large, complex molecular structures
