Automated Peptide Microarray Printing for Epitope Mapping

Epitope Mapping: Importance and Challenges

Epitope mapping is a critical process for identification and characterization of antibodies, antigens, and other protein binding sites. This information allows scientists to develop novel therapeutics and vaccines for various viral pathogens, while also being a powerful approach for understanding how antibodies are produced as a response to different conditions (including cytotoxins, allergens, neuronal or inflammatory). However, epitope identification and mapping can be difficult due to the complexity of protein and peptide structures. Current methods for epitope mapping, including X-ray co-crystallography, cryogenic electron microscopy (cryo-EM), and site-directed mutagenesis mapping, can be excessively time-consuming and expensive. To improve efficiency, Aurora has developed a flexible automated peptide microarray workstation to facilitate processes such as epitope mapping.
