Matrix-assisted laser desorption mass spectrometry of HMW-Cd·GS. MALD-MS was performed on Sephadex G-15-, Mono-Q-purified HMW-Cd·GS as described. The molecular structure inferred from a mean m/z ratio of 725.4 ± 0.7 (n = 9) and average Cd/GS stoichiometry of 0.5 (Cd·GS2, molecular weight 724.6 Da) is shown.
