Protein glycosylation is known to rapidly change in disease, as well as in cancer progression. Therefore, heavily glycosylated tumor-derived circulating proteins hold a great potential to perform as “disease ambassadors” in the bloodstream, enabling more sensitive and specific diagnostics. However, proper characterization is challenging due to low quantity in serum and the high heterogeneity of the glycan distribution. Here, we present a comparison between different analytical platforms for the in-depth characterization of two glycoproteins (carcinoembryonic antigen and laminin B1). Further studies will examine if altered glycosylation profiles of these glycoproteins can be used as prognostic tools for colorectal cancer.
