Matrix assisted laser desorption ionization time of flight mass spectrometry(MALDI-TOF-MS, model AXIMA CFR+) was used to analyze galactosyl-HSA (human serum albumin) synthesized in our laboratory. It clearly showed that HSA covalently combined with galactoses. Galactosyl-HSA is pure and the ratio of galactosyl residues to protein is 48:1.
