Li L, Liu Y, Ma C, Qu J, Calderon AD, Wu B, Wei N, Wang X, Guo Y, Xiao Z, Song J, Sugiarto G, Li Y, Yu H, Chen X, Wang PG.
PMID: 26417422
Chem Sci. 2015 Oct 01;6(10):5652-5661. doi: 10.1039/C5SC02025E. Epub 2015 Jun 23.

Quantification, characterization and biofunctional studies of N-glycans on proteins remain challenging tasks due to complexity, diversity and low abundance of these glycans. The availability of structurally defined N-glycans (especially isomers) libraries is essential to help on solving these tasks....
