Monoclonal Antibodies: Faster Analysis with Microdroplets
The first reported combination of microdroplet reactions with ECD fragmentation offers a quicker way to analyze monoclonal antibodies for disease treatments. Thomas Walker from Agilent Technologies and co-workers demonstrate the use of an Agilent Jet Stream electrospray ionization source to facilitate in-spray chemical reduction and protease digestion of monoclonal antibodies. Downstream fragmentation of the microdroplet reaction products with ECD provided rapid characterization of intact antibodies in minutes. Efficient ECD fragmentation yielded rich sequence information including evidence of disulfide bond connectivity and confirmation of key sequences called complementary determining regions. These results highlight this method’s potential for fast and cost-effective antibody characterization with minimal sample preparation.
