New insights into chitosan-DNA interactions using isothermal titration microcalorimetry.
The interaction of chitosan with plasmid DNA was investigated as a function of pH, buffer composition, degree of deacetylation (DDA), and molecular weight (M(n)) of chitosan, using isothermal titration microcalorimetry (ITC). The Single Set of Identical Sites model was used to obtain the enthalpy of interaction, the binding constant, and the stoichiometry of binding. The chitosan-DNA interactio...
متن کاملFoaming and adsorption behavior of oppositely charged surfactant mixtures
Although the application of liquid foams is widespread, too little is yet understood about stability control. One promising way to tune their properties is the application of oppositely charged surfactant mixtures. These catanionic surfactant mixtures show a strong synergism. This makes them eco-friendly since it allows reducing the required amount of surfactant. Due to the formation of surface...
متن کاملStandards in Isothermal Microcalorimetry
The main calorimetric principles used in isothermal microcalorimetry are briefly discussed. Different chemical calibration and test reactions are discussed, with a focus on reactions suitable for ambient conditions: reactions initiated by mixing of liquids (including titration microcalorimetry), dissolution of solid compounds and of slightly soluble gases, a photochemical process, and thermal p...
متن کاملIsothermal titration calorimetry: experimental design, data analysis, and probing macromolecule/ligand binding and kinetic interactions.
Isothermal titration calorimetry (ITC) is now routinely used to directly characterize the thermodynamics of biopolymer binding interactions and the kinetics of enzyme-catalyzed reactions. This is the result of improvements in ITC instrumentation and data analysis software. Modern ITC instruments make it possible to measure heat effects as small as 0.1 microcal (0.4 microJ), allowing the determi...
متن کاملOrganized assemblies in bolaamphiphile/oppositely charged conventional surfactant mixed systems.
Five ionic bolaamphiphiles were synthesized and the aggregation behavior of bola single systems and bola/oppositely charged conventional surfactant mixed systems was studied. Small spherical vesicles were formed in all these mixed systems revealed by transmission electron microscopy (TEM). Variation of the structure of the hydrophobic chain of bolaamphiphiles has great influences on the vesicle...
