Normal phase
Resolves glycans based on hydrophilicity, which is determined primarily by size, as well as arm specificity and linkage. Used for glycoprofiling of LudgerTag 2-AA and 2-AB labeled glycans showing the relative amount and size of all glycans released from the glycoprotein.
Anion exchange
LudgerSep columns and buffer for charge profile analysis of 2-AA and 2-AB labeled glycans. The number of sialic acids per glycan is the primary factor in the analysis.
