General description

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.

Application

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_238^T(34)

Generic nitric oxide (NO) generating surface by immobilizing organoselenium species via layer-by-layer assembly.

Jun Yang et al.

Langmuir : the ACS journal of surfaces and colloids, 24(18), 10265-10272 (2008-08-20)

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

Biotechnology and bioengineering, 85(6), 601-609 (2004-02-18)

The human gene encoding the mature form of bone morphogenetic protein-2 (hBMP-2), a dimeric disulfide-bonded protein of the cystine knot growth factor family, was expressed in recombinant Escherichia coli using a temperature-inducible expression system. The recombinant protein was produced in

High-throughput assay of nitric oxide metabolites in human plasma without deproteinization by lab-on-a-chip electrophoresis using a zwitterionic additive.

Takashi Miyado et al.

Journal of chromatography. A, 1206(1), 41-44 (2008-08-12)

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

Factors influencing the choice of buffer in background electrolytes for indirect detection of fast anions by capillary electrophoresis.

P Doble et al.

Electrophoresis, 19(12), 2257-2261 (1998-10-07)

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
