Ci2H25S0itNa (NaDDS) from B.D.H. or Serva (Germany) Na-deoxy-cholate (NaDOC) from Sigma Cetyl trimethylammonium bromide (CTAB) from Schuchardt, were used as supplied by the respective manufacturer (over 99 % purity). Distilled water was used after treatment with the Millipore Q filter. 

Acid detergent solution - add 100 g cetyl trimethylammonium bromide (CTAB), also called hexadecyltrimethylammonium bromide, technical grade, to 2.5 I of 1 M sulphuric acid, stir to dissolve and make up to 5 I... 

Gutsche et al. observed that a lipophilic dioxime (the ligand in 4) accelerates by a factor of 60 to 140 the hydrolysis of acetyl phosphate in the presence of an equimolar amount of metal (M = Cu, Zn, Ni) under comicellar conditions with cetyl trimethylammonium bromide (CTAB) at pH 11.5 [22], The hydrolysis reaction was followed by pseudo-first-order kinetics at [ligand] = [M] = 2.5 mM and [CTAB] = 250 mM. Although a possible complex 4 was proposed to exist in the hydroxamate form, there were no experimental data for the stability and structure of metal complexes at pH 11.5 (e.g., it is not known whether the...

To extend the utility of reverse micelles to those samples that require detergent or lipid to prevent aggregation and promote folding, reverse micelle formulations have recently been introduced that use detergents capable of forming regular aqueous-phase micelles (e.g., LDAO, dodecyl- or cetyl-trimethylammonium bromide (DTAB or CTAB, respectively)) [228]. These can be used to solubilize membrane proteins in the aqueous micelle conditions usually used during purification. 

For bioappUcations, UCN should be hydrophilic, biocompatible and should possess functional groups to facilitate covalent bioconjugations [30]. Most of UCN are synthesized in organic solvents [5,41,42] or at high temperatures [30,33]. Organic surfactants such as cetyl-trimethylammonium bromide (CTAB) or ethylenediamine tetra acetic add (EDTA) are often used as ligands to control the particle growth and...
