Dr. Guan-Da Syu's lab, is about using Protein Array in Research, Diagnosis, and Drug (PARDD) development. Many novel platforms have been developed, such as protein microarray for GPCRs, coronavirus protein microarray for testing COVID-19, and flavivirus protein microarray for accessing severe dengue cases. Recently, we developed a SARS-CoV-2 variant protein microarray for evaluating neutralizing antibodies against various VOCs after COVID-19 vaccines. Anyone who's interested in these aspects is welcome to join or collaborate.
