Fructose-bisphosphate aldolase C is one of important glycolytic isozymes in the metabolic process. The fructose-bisphosphate aldolase C which highly expressed in the human ovarian adenocarcinoma cell has been separated by two-dimensional gel electrophoresis and identified by matrix-assisted laser desorption ionization tandem time-of-flight mass spectrometry (MALDI-TOF/TOF MS). The results indicate that MALDI-TOF/TOF MS in combination with the high resolution two dimensional gel electrophoresis is a simple and fast method for identification of unknown proteins.

Key words: aldolase C, matrix-assisted laser desorption ionization tandem time of flight mass spectrometry, two dimensional gel electrophoresis
