Multifaceted evaluation to ensure the quality and safety of antibody pharmaceuticals.
High-precision measurement of size variants, aggregates, and stability using light scattering detectors and LC-MS.
In the development of antibody drugs and antibody-drug conjugates (ADCs, etc.), it is essential to maximize the efficiency of the development process while ensuring the quality and safety of the products. By using light scattering detectors to evaluate size variants, aggregates, stability, and other factors from the early stages of development, it is possible to identify the characteristics of potential candidate antibodies early on and avoid risks and dropouts in the later stages of development. Combining this with LC-MS allows for even more comprehensive characterization.
