Here, we present several modified glycoproteomic protocols that differ, for example, in the purification step, the enzyme used, and the digestion procedure with the aim of efficient and sensitive analysis of N-linked glycans. Ribonuclease B of different concentrations was chosen as a model glycoprotein.The most successful protocol was based on DTT reduction during thermal denaturation. In addition, two reducing agents (DTT and TCEP) were compared, but no significant results were observed.
