The development of monoclonal antibody (Mab) based drugs has undergone considerable growth since the release of the first Mab in the mid-eighties. Intuitive biophysical tools that examine and quantify interactions and conformational dynamics are important in demonstrating and understanding local and global conformational changes. The structure of antibodies as well as other macromolecules is related to its function and efficacy therefore control over these parameters is essential. The association of antigens to antibodies or of antibodies to delivery assemblies such as liposomes or gold nanoparticles can be addressed by isothermal titration calorimetry (ITC) while the folding of antibodies can be assayed using differential scanning calorimetry(DSC). Both techniques offer the advantage of using native solutionsand both instruments are offered by TA Instruments.
