GEMMA == Gas-phase Electrophoretic-Mobility Macromolecule Analysis Described in PMID: 16861739, used also in PMID: 19913479

Citing after the first one: GEMMA is a method to study protein complexes in solution: a diluted protein sample is transmitted into the gas phase by a charged reduced electrospray process. The generated particles, each containing one protein molecule with a +1 charge, are separated according to size in a differential mobility analyzer and subsequently quantified by a particle counter. In contrast to mass spectrometry, this method is run at atmospheric pressure and measures the diameter of the particle rather than the mass.

As this method is related to other electrophoretic methods it might make sense to modify the hierarchy of terms to look, more or less, like:

biochemical (MI:0401) electrophoretic mobility-based method (new) comigration in gel electrophoresis (MI:0807) ... comigration in gas phase electrophoresis (new) GEMMA (new)
