Abstract

The prospects of detecting and quantifying peptides and proteins were studied using ionic liquids as matrices for MALDI-MS. Ionic liquids of α-cyano-4-hydroxycinnamic acid (CHCA) were prepared by dissolving 0.5g of acid in 15 mL methanol. Bradykinin and Tyr-bradykinin were chosen as test analytes and internal standards. MALDI-TOF spectra from positive and negative-ion modes verified the molecular weights of all ionic liquids.
