With similar properties to the Octet^® SPR CDH sensor chip, the Octet^® SPR PCH sensor chip has a greater degree of surface carboxylation and a denser matrix, resulting in a significantly higher binding capacity. Comprised of a non-dextran polycarboxylate hydrogel surface, it provides an alternative to dextran-based

sensor chips. This makes it ideal for small molecule, fragment and low molecular weight research, as well as experimentation involving low analyte concentrations or unfavourable immobilization conditions.
