一般描述
CHES (2-(Cyclohexylamino) ethane sulfonic acid) is a derivative of amino acid taurine. It serves as a standard physiological buffer in the pH range of 8.5-9.5.
应用
CHES may be used:
- for pH adjustments and as a assay buffer in catechol oxidase activity measurements(32)
- as a buffer in electron paramagnetic resonance (EPR) spectroscopy and kinetic measurements(33)
- as a buffer for soil solution equivalent (SSE) yeast dextrose medium for screening pH optima for growth of Aridibacter nitratireducens A24_SHP-5_238T(34)

A systematic evaluation of continuous flow-counterbalanced capillary electrophoresis for microscale preparative applications is presented. The success of the technique was found to depend on the specific nature of the analyte and background electrolyte and was most heavily influenced by factors

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

Several glycosphingolipids were labeled with the fluorphore Bodipy-Fl and analyzed using capillary electrophoresis with laser-induced fluorescence detection. GM1-, LacCer-, and Cer-Bodipy-Fl were prepared through acylation using the N-hydroxysuccinimide ester of Bodipy-Fl. Several other glycosphingolipids including GT1a-, GD1a-, GM2-, GM3-, GD3-

Much is unknown concerning the role of thiolate ligands of molybdenum in molybdopterin enzymes. It has been suggested that thiolate dissociation from molybdenum is part of the catalytic mechanism of bis-molybdopterin enzymes of the dimethyl sulfoxide reductase (DMSOR) family. For
