Descrição geral

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.

Aplicação

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 universal nitric oxide (NO) generating surface is assembled via Layer-by-Layer (LbL) deposition of sodium alginate (Alg) and organoselenium modified polyethyleneimine (SePEI) on quartz and polymeric substrates. The immobilized SePEI species is capable of catalytically decomposing S-nitrosothiol species (RSNO) to

In order to develop a high-throughput assay for nitric oxide metabolites, nitrite (NO2-) and nitrate (NO3-), in biological fluids, we have investigated the simultaneous determination of them using an electrophoretic lab-on-a-chip (microchip capillary electrophoresis, MCE) technique. In this study, in

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
