Achieving insights into the structure of proteins and protein macromolecular complexes is critical in understanding the relationship with their biological function.
Using either HDX-MS or Native MS analysis, the SELECT SERIES Cyclic IMS can help your lab learn about the physical size and shape of proteins, and is ideal for modeling protein assembly structures that are difficult and time-consuming to study with conventional structural biology approaches.
For studying protein unfolding and subunit configurations, the Cyclic IMS can be configured with an array of ion activation techniques, including electron capture dissociation (ECD), surface induced dissociation (SID), and collision-induced dissociation (CID). All of these techniques combine with scalable ion mobility and IMSn to deliver unique insights in structure.
