Abstract: Abstract: As one of the most important and common post-translational modifications， protein glycosylation plays an essential role in biological function. The changes of glycoprotein content and/or glycosylation degree as well as alterations of glycan structure are associated with a variety of diseases. Therefore， increasing attention has been directed to the quantitative and comparative aspects of glycoproteome. However， the quantitative glycoproteomics faces more severe challenges because of the intrinsic characteristics of glycoproteins. The development of technologies and methods of quatititative glycoproteomics will increasingly become an important tool for the biological function study of glycoprotein. Advantages and disadvantages of several newly developed technologies and methods were discussed， and the progress in quantitative glycoproteome research was summarized.
