Revealing the changes of IgG subclass‐specific N‐glycosylation in colorectal cancer progression by high‐throughput assay

The changes of glycosylation of different IgG subclass in colorectal cancer (CRC) were rarely investigated. The authors aimed to use a simple and high-throughput analytical method to explore the changes of subclass-specific IgG glycosylation in CRC, and to find the specific glyco-biomarkers for early detection of this disease.
