Detergents assisted glycoprotein capture


ABSTRACT: A detergents assisted glycoprotein capture method was developed to increase the coverage of N-glycoproteome of various samples.Application of this approach in the larger scale N-glycoproteomics analysis of the HEK 293 cell membrane led to the identification of 2253 unique N-glycosites from 953 proteins. Application of this approach to human serum resulted in the identification of 850 N-glycosylation sites without any immuno-depletion and fractionation.

Large-scale N-glycoproteome studies have been hindered by poor solubility of hydrophobic membrane proteins and the complexity of proteome samples. Herein, we developed a detergent-assisted glycoprotein capture method to reduce these issues by conducting hydrazide chemistry-based glycoprotein capture in the presence of strong detergents such as sodium dodecyl sulfate and Triton X-100. The strong detergents helped to solubilize hydrophobic membrane proteins and then increased the access of hydrazi  ...[more]
