Biophysical Studies on the Interaction of Insulin with a Cationic Gemini Surfactant
A novel quaternary ammonium-based cationic gemini surfactant (S6) having 1,6 di-bromo hexane as a spacer, have been used and its interaction with insulin in aqueous solution (pH, 7.40) was investigated by several methods including fluorescence spectroscopy, UV-Vis spectroscopy, circular dichroism, dynamic light scattering, ζ-potential measurements, conductivity and transmission electron microsc...
متن کاملSpontaneous aggregate transition in mixtures of a cationic gemini surfactant with a double-chain cationic surfactant.
Controllable aggregate transitions were realized by mixing two kinds of cationic surfactants, hexylene-1,6-bis(dodecyldimethylammonium bromide) (C(12)C(6)C(12)Br(2)) and didodecyldimethylammonium bromide (DDAB). It was found that two parameters are the main factors determining the aggregation behavior of the mixed system, the total concentration of DDAB and C(12)C(6)C(12)Br(2) (C(T)), and the m...

متن کاملHydrodynamic size of DNA/cationic gemini surfactant complex as a function of surfactant structure.
The present study deals with the determination of hydrodynamic size of DNA/cationic gemini surfactant complex in sodium bromide solution using the dynamic light scattering method. Cationic gemini surfactants with polymethylene spacer of variable length were used for the interaction with DNA. The scattering experiments were performed at constant DNA and sodium bromide concentrations and variable...
متن کاملWhole blood targeting and activation of monocytes with TLR7 agonist formulated in cationic liposomes
Monocytes are one of the major phagocytic cells in the periphery that patrols the circulation for invading pathogens, and upon activation differentiates into dendritic cells, capable of migration to lymph nodes eliciting an adaptive immune response. Monocytes has for more than a decade been precursor cell for generation of autologous dendritic cell cancer vaccines, but clinical results have sho...
