Microwave radiation is used to lyse and extract dipicolinic acid (DPA) and lipids from Bacillus subtilis spores in one minute. Molecular analysis is by nESI-MS with DPA being confirmed by MS/MS at levels as low as 105–106 spores.

One of the major factors governing the "top-down" sequence analysis of intact multiply protonated proteins by tandem mass spectrometry is the effect of the precursor ion charge state on the formation of product ions. To more fully understand this eff
