Tandem differential mobility analysis-mass spectrometry reveals partial gas-phase collapse of the GroEL complex.

Tandem differential mobility analysis-mass spectrometry reveals partial gas-phase collapse of the GroEL complex.

A parallel-plate differential mobility analyzer and a time-of-flight mass spectrometer (DMA-MS) are used in series to measure true mobility in dry atmospheric pressure air for mass-resolved electrosprayed GroEL tetradecamers (14-mers; ~800 kDa). Narrow mobility peaks are found (2.6-2.9% fwhm); hence...
