Protein misfolding (IMAGE) University of Massachusetts Amherst Caption In this cell assay, Woerman is able to visualize protein misfolding by tagging a protein of interest with yellow fluorescent protein. The bright yellow puncta in the images are protein aggregates. "Our goal is to develop a gene therapy that stops that process from happening," Woerman says.
