The desired candidate will have a solid understanding and hands-on work experience with all aspects of biologics downstream process development, including protein purification/characterization, process chromatography, tangential flow filtration, depth filtration operations, and preferably with some analytical skills such as SDS-PAGE, western blot, mass spectrometry, and dynamic light scattering. Preferably have some experience developing affinity-based in-process assays using technologies such as bio-layer interferometry and/or surface plasmon resonance, evaluating protein identity and modifications by mass spectrometry, protein aggregation by dynamic light scattering.
