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

The suitability of relatively slow (low absolute value of mobility) coanionic buffers in background electrolytes (BGEs) for indirect photometric detection of anions by capillary electrophoresis was investigated. As a model system, 2-(cyclohexylamino)ethanesulfonic acid (CHES) was used to buffer the indirect
