To control the surface charge, we chose a positively charged N-[1-(2,3-dioleoyloxy)propyl]-N,N,N- trimethylammonium
methyl-sulfate (DOTAP), negatively charged diacetyl phosphate (DCP), and neutral 1,2-dioleoyl-sn-glycero-3-phosphoethanolamine (DOPE), to make up the remainder of the lipid mixture.
Sicsic, "Chemical modification of chitosan by glycidyl trimethylammonium
reported that DC stimulation by cationic liposomes composed of DOTAP (1,2dioleoyl-3- trimethylammonium
propane) also stimulated reactive oxygen species (ROS), which activated extracellular signal-regulated kinase (ERK) and p38, and downstream proinflammatory cytokines/chemokines, interleukin-12 (IL12), and chemokine (C-C motif) ligand 2 (CCL2) .
One can notice that all studied compounds possessing cationic (onium: trimethylammonium
, methylcycloalkylammonium, or pyridinium) substituents at 2 and 6 methylene of the DHP cycle have more or less significant ARA.

Furthermore, we employed (3-chloro-2-hydroxypropyl) trimethylammonium
chloride to functionalize the as-prepared aerocelluloses to immobilize negatively charged dye molecules for wastewater clarification.
In order to study the heart disorder, Agladze's team created "arrhythmia in vitro", using azoTAB (azobenzene trimethylammonium
bromide) whose molecule consists of two benzene rings connected by a bridge of two nitrogen atoms, said the study published in the journal PLOS ONE.
CTAB (Cetyl trimethylammonium
bromide), TEOS (Tetraethyl orthosilicate) were purchased from Merck.
Improved detection of rhamnolipid production using agar plates containing methylene blue and cetyl trimethylammonium
For instance, cetyl trimethylammonium
bromide (CTAB) buffers including a reduction agent such as P-mercaptoethanol have been tested alone or in combination with either polyvinylpyrrolidone (PVP), or polyvinylpolypyrrolidone (PVPP) (STADDON et al., 2004; TURRINI et al., 2008).
The resin Dowex AG1X8-100 with a quaternary trimethylammonium
exchange group and chloride as counter ion was selected for extraction and concentration of GLYP and AMPA and, the pH should be optimized to permits to maximum analytes retention as AMPA and GLYP may have positive and negative charge depending on pH.
