Rapid and High-Throughput N-Glycomic Analysis of Plant Glycoproteins

Glycoprotein is a major element in higher organisms including mammalians and plants. It is widely accepted that variation in cellular N -glycome is related to modulation in dynamic cellular mechanisms such as cell-cell adhesion, cell activation, and malignant alterations in mammalian cells. However, the physiological importance of glycan modification of glycoproteins in plant cells is still a matter of dispute. Therefore, a comprehensive and high-throughput analysis of N -glycome in plant glycoproteins is needed. Here, an application of the glycoblotting-mass spectrometry technique to plant glycoprotein research is described.
