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.

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) [99].
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.

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.
