A variety of gram-positive and gram-negative intact bacterial cells have been analysed by matrix-assisted laser desorption/ionization mass spectrometry (MALDI-MS) and shown to provide fingerprint mass spectra with discrete peaks being observed over the mass range from 3 to 40 kDa.
Matrix-assisted laser desorption ionization mass spectrometry with 2-(4-hydroxyphenylazo) benzoic acid matrix.

The tautomeric equilibria of 2-(4'-hydroxyphenylazo)benzoic acid (HABA) and 2-(3',5'-dimethyl-4'-hydroxyphenylazo)benzoic acid (3',5'-dimethyl-HABA) have been studied by a combination of spectroscopic and computational methods. For neutral HABA in solvents of different polarity (toluene, chloroform, DMSO, DMF, butanol, and ethanol) the azo tautomer
