Biochemistry Innovation: Using Advanced Protein Purification for Structural Biology Research

Learn how our cutting-edge protein concentration methods helped support the research of protein-protein interactions at the City University of New York.


Pall’s centrifugal filters helped support Kwangwoon Lee, at the City University of New York focus on protein interactions at the peptide level. They were able to purify and concentrate specific protein fractions before studying them using Nuclear Magnetic Resonance (NRM) spectroscopy.
