In this work, we report the effect of different proteomic protocols varying in enzyme or digestion procedures followed by derivatization by Cascade Blue hydrazide (8-(2-hydrazino-2-oxoethoxy)pyrene-1,3,6-trisulfonic acid trisodium salt, CBH) on the glycan detection in CE/LIF analysis. CBH represents a more reactive analog of APTS widely used for glycan labeling before CE analysis [1]. Ribonuclease B was selected as a model glycoprotein and four digestion protocols (alkylation, in gel/in solution treatment, purification step, etc.) were applied in order to obtain highly sensitive detection of labeled glycans by CE/LIF analysis.
