CTAB precipitation of cestode DNA
Parasitology Today, 1987DNA probes are proving extremely valuable in the characterization o f cestodes - as well as other parasites. In this article, Kok Wei Yap and Andrew Thompson discuss some of the problems of DNA isolation, stressing the need for a gentle and economical procedure such as CTAB precipitation.

Structure and stoichiometry of CTAB–DNA complexes
The Journal of Chemical Physics, 2020We have studied the structure of cetyltrimethylammonium bromide–DNA complexes using small angle x-ray diffraction and elemental analysis. These complexes exhibit a two-dimensional hexagonal phase. The diffraction data have been analyzed using electron density models based on two different structures of these complexes proposed in the literature, which ...

Effect of CTAB and procain hydrochloride on neutral red microstructure in CTAB micelle
Colloid Journal, 2008The effects of cationic surfactant (CTAB) and procaine hydrochloride on the microstructures of neutral red (NR) are studied by UV-Vis spectroscopy, fluorescence spectroscopy and surface tension and conductivity measurements. The obtained results show that the acidic structure of NR can be gradually transformed to its neutral structure with an increase ...

Effect of CTAB and CTAB in the presence of hyaluronan on selected human cell types
Colloids and Surfaces A: Physicochemical and Engineering Aspects, 2014Abstract The effect of different concentrations of CTAB (in the range of 0.2 mM −2 mM, i.e., including its critical micelle concentration) on viability of selected human cells (osteoblasts and keratinocytes) was studied by a variety of methods (immunocytochemical and biochemical), testing the cell viability and the metabolism, to get a complex ...

Cold Spring Harbor Protocols, 2010
INTRODUCTIONAlthough SDS-PAGE is the method of choice for most denaturing gel electrophoresis procedures, the anionic detergent SDS still presents some drawbacks. For example, SDS forms crystals at low temperatures and, in some cases, causes proteins to aggregate or precipitate.

Structure of DNA-CTAB-hexanol complexes
Physical Review E, 2006We have probed structures of the complexes formed by DNA with the cationic surfactant cetyltrimethylammonium bromide in the presence of the cosurfactant hexanol, using small angle x-ray diffraction techniques. They are found to exhibit a hexagonal-->lamellar-->hexagonal transition with increasing hexanol content.

Adsorption of phenol by MMT-CTAB and WPT-CTAB: Equilibrium, kinetic, and thermodynamic study
Particulate Science and Technology, 2017ABSTRACTIn this study, the phenol adsorption capacity of cetyltrimethylammonium bromide modified clays (MMT-CTAB) and cetyltrimethylammonium bromide modified pulp tea (WPT-CTAB) were studied. In batch adsorption experiments performed with MMT-CTAB, the effects of parameters such contact time, phenol concentration, pH of solution and adsorbent dosage ...

Ultrasonic Studies of Ctab in Glycol
Molecular Crystals and Liquid Crystals, 2003Ultrasonic absorption and velocity measurements have been made in cetyl trimethyl ammonium bromide (CTAB) in nonaqueous solution of ethylene glycol as a function of concentration, temperature, and at a fixed frequency. The interferometer technique has been used to measure ultrasonic velocity at 2 MHz.

The interaction between morin and CTAB aggregates
Journal of Colloid and Interface Science, 2005Electronic absorption spectra, fluorescence emission spectra, ATR-FTIR spectra, cyclic voltammetric measurements, and ab initio quantum calculation are used to study the properties of morin in CTAB micelles with different microstructures and microenvironments and to gain information about the binding of morin with CTAB micelles. Morin can be located in

The dynamical landscape in CTAB micelles
Soft Matter, 2012Here we report molecular dynamics of cetyltrimethylammonium bromide (CTAB) based cationic micelles as studied using an incoherent quasielastic neutron scattering (QENS) technique. Data as obtained from two different spectrometers, IRIS at the ISIS facility, UK, and FOCUS at SINQ, PSI, Switzerland, having energy resolutions, ΔE ≈ 17.5 μeV and 55 μeV ...
