Dr. Wu joined Pure Protein L.L.C. in 2017. As an Immunologist with more than 20 years of experience, he is currently applying his broad technical expertise to the manufacturing of HLA proteins at small, medium, and large scale. In addition to being a production and purification expert, he is also involved in antibody and HLA matrix coupling; the conjugation of HLA with biotin and fluorophores; engineering of HLA peptide complexes; and T-cell peptide epitope validation and screening. Being responsible for sHLA quality control, Dr. Wu employs many immunoassays to confirm the integrity of HLA protein products. Dr. Wu also has extensive experience in flow cytometry techniques currently applied in the development of tetramer products for B cell and T cell detection.

Dr. Wu received his Ph.D. in Microbiology and Immunology from the National Yang-Ming University of Taipei, Taiwan in 2005. He served as a postdoctoral fellow at Academia Sinica in Taiwan, and at Beth Israel Deaconess Medical Center in Boston until 2009. After four years of service, he accepted a research position at Oklahoma Medical Research Foundation (OMRF) in Oklahoma City before joining Pure Protein. Dr. Wu has published many papers in high-profile international journals including the Journal of Immunology, Journal of Experimental Medicine, Plos One, Journal of Biological Chemistry, and others.
