| الملخص≠ | Circular Dichroism (CD) spectroscopy measures the differential absorption of left- and right-circularly polarized light by optically active molecules, particularly proteins and nucleic acids. Introduced by Greenfield and Fasman in 1969, CD is a rapid, non-destructive technique for characterizing secondary structure (alpha-helix, beta-sheet), monitoring protein folding transitions, and assessing conformational changes in response to pH, temperature, or ligand binding. | Isothermal Titration Calorimetry (ITC) is a thermodynamic technique that measures heat released or absorbed during biomolecular binding events at constant temperature. Developed by Wiseman and colleagues in 1989, ITC directly determines binding affinity (Kd), enthalpy (ΔH), and entropy (ΔS) in a single experiment, making it one of the most comprehensive methods for characterizing molecular interactions without requiring labels or immobilization. |
