General description
CHES (2-(N-cyclohexylamino)ethanesulphonic acid) is regarded as Good′s buffers for its self-buffering and biocompatible feature. It is used in protein stabilization and does not interact with metals.
Application
CHES has been used:
- as a buffer in mannanase activity assay of antarctic fungal isolates
- as a buffer for DNA digestion and labeling of 2′-deoxyadenosine 3′-monophosphate
- as a component of Wilson and Horne extraction buffer for characterization of rat plasma enzymes
