effects of ?-cyclodextrin, ?cd, on refolding of lysozyme was investigated at ph 12 employing isothermal titration calorimetry (itc) at 300k in 30mm tris buffer solution. ?cd was employed as an anti-aggregation agent and the heats obtained for lysozyme+?cd interactions are reported and analyzed in terms of the extended solvation model. it was indicated that there are two sets of identical and no...

Isothermal titration calorimetry (ITC) is a popular chemical analysis technique that can be used to measure macromolecular interactions and physical processes. ITC involves the measurement of heat flow from cell after each injection during experiment. has been useful thermodynamics such as protein-ligand or protein-protein binding affinity also processes enzyme catalyzed reactions. The use in b...

Isothermal titration calorimetry (ITC) is a fast and robust method to study the physical basis of molecular interactions. A single well-designed experiment can provide complete thermodynamic characterization of a binding reaction, including K(a), DeltaG, DeltaH, DeltaS and reaction stoichiometry (n). Repeating the experiment at different temperatures allows determination of the heat capacity ch...

Current Isothermal Titration Calorimetry (ITC) data in the literature have relatively high errors in the measured enthalpies of protein-ligand binding reactions. There is a need for universal validation standards for titration calorimeters. Several inorganic salt co-precipitation and buffer protonation reactions have been suggested as possible enthalpy standards. The performances of several com...

a binding study of nickel ions by a new recombinant human growth hormone (hgh), produced as an injected drug, has been done at 27˚c in nacl solution (50 mm) using an isothermal titration calorimetry. there is a set of three identical and non-interacting binding sites for nickel ions. the intrinsic dissociation equilibrium constant and the molar enthalpy of binding are 40 μm and -16.5 kj/mol, re...
