CHI’s “Structure-Based Optimization of Antibodies” is a 3-hour course that offers a quick overview of the concepts, strategies, and tools of structure-based optimization of antibodies. This lecture will cover structure-based techniques to modulate affinity, create novel constructs (such as Fc-fusions, bispecifics, etc.) along with increasing the manufacturability of a biologic. The class is directed at scientists new to the industry, academic scientists, and career protein engineers wanting a quick overview about how structure can aid in guiding experimental design.
