In order to study thermodynamics of protein misfolding-induced aggregation and establish a new assay, isothermal titration calorimetry (ITC) was performed on amyloidogenesis of several amyloidogenic proteins and peptides. I revealed that amyloid formation resulited in exothermic heat after the lag time, and obtained thermodynamic parameters such as the change in enthalpy using in-house algorithms. I further challenged to elucidate the kinetic property of amyloid formation, and could calculate the rate constant of nucleation and elongation of amyloid fibrillation. Energy landscape built using these parameters revealed the polymorphic amyloidogenesis of b2m.ITC-based assay provides a powerful method for the study of the thermodynamics, kinetics, and mechanism of protein aggregation.
