Anne-Frances Miller: Spinning Toward Success

“So, instead of having to analyze an entire protein, you can take a shortcut and focus your measurements just on the active site,” she continues. This “smart” DNP, as Miller refers to it, should make the technique more applicable than ever, as a researcher won’t need large quantities of protein or even a pure sample. Only protein molecules containing the flavin would be evident in a DNP-NMR spectrum.
