A scientist has spent months trying to determine the 3D structure of a large membrane protein.However, despite extensive purification, the protein fails to form crystals, making structural analysis by traditional methods impossible. Which approach is most likely to yield a high-resolution structure without requiring crystals?  

You are purifying a protein that carries a net positive charge at physiological pH (~7.4). The chromatography buffer is maintained at pH 7.4 throughout the experiment. You have access to both cation- and anion-exchange chromatography systems: Cation exchanger: Negatively charged stationary phase (column) Binds positively charged molecules Anion exchanger: Positively charged stationary phase (column) Binds negatively charged molecules   If your goal is to retain the protein on the column during purification, which approach should you choose, and why?
