probable use of chemical and biochemical detergents to wash polysulphone membranes using in milk ultrafiltration needs a multidisciplinary investigation. by increasing use of these membranes in food processing, washing and recovery of initial permeate flux, in order to use for a longer time from this technology, has much importance. in this research, influence of chemical detergents including e...

N-d-Gluco-N-methylalkanamide detergents have been synthesized. The detergents, which were produced in high yield and at low cost, compared favourably in biochemical studies with commonly used non-ionic detergents, including a chemically related n-alkyl glucoside. The ease of removal by dialysis, high solubilizing power and non-denaturing properties of this new class of detergents make them valu...

MICROCALORIMETRY Introduction Many industrial and biochemical applications depend on the usage of detergents and other surfactants. These compounds are indispensable, in particular, for the extraction, purification, and handling of membrane proteins. Owing to their amphiphilic nature, detergents can provide a membrane-mimetic environment required by integral membrane proteins to retain their na...

In membrane protein biochemical and structural studies, detergents are used to mimic membrane environment and maintain functional, stable conformation of membrane proteins in the absence of lipid bilayers. However, detergent concentration, esp. molar ratio of membrane protein to detergent is usually unknown. Here, a gas chromatography-mass spectrometry selected ion monitoring (GC-MS-SIM) method...

conclusions with the proper operation of wastewater the treatment plant and increasing the retention time, the removal efficiency of the detergents increased. in addition, according to the environmental standards for bod5, cod and the detergents, the results of the present study indicated that the outputs of these parameters from the sbr system were appropriate for agricultural irrigation. resu...

Understanding the membrane solubilization process and finding effective solubilizing agents are crucial challenges in biochemical research. Here we report results on the interaction of the novel linear alkylamido propyl dimethyl amino propanosulfonate detergents, ASB-14 and ASB-16, with human erythrocyte membranes. An estimation of the critical micelle concentration of these zwitterionic deterg...

Determination of protein concentration is often an absolute prerequisite in preparing samples for biochemical and proteomic analyses. However, current protein assay methods are not compatible with both reducers and detergents, which are however present simultaneously in most denaturing extraction buffers used in proteomics and electrophoresis, and in particular in SDS electrophoresis. It was fo...
