We report the observation of a wide range of single and mixed molecula
r cluster ions with mass extending up to about 250 000 u in matrix-ass
isted laser desorption ionization time-of-flight mass spectrometric an
alysis of protein mixtures. These duster ions of mixed composition hav
e been generated with a number of different pairs of simple analyte pr
oteins (M < 150 000 u) in the presence of several matrices and at a ra
nge of matrix-analyte dilutions.
