Natural Glycans for Functional Glycomics
Project Summary/ Abstract
During the first decade of the 21st century, NIH made significant investments in glycomics. The Consortium for
Functional Glycomics (supported by NIGMS 2001-2012) led a major international effort using a microarray of
611 defined glycans to identify the protein-glycan interactions associated with normal physiology and disease
(http://www.functionalglycomics.org/CFGparadigms/index.php/Welcome_to_the_CFG_Paradigm_Pages). This
611 glycan library transformed studies on protein-glycan interactions and revealed the importance of defining
the human glycome, estimated to be in the range of 10,000 determinants. A microarray comprised of all possible
glycans would allow us to detect and define all physiologically relevant glycan binding proteins (GBP), but the
CFG library is now only 575 glycans making the production of large quantities of pure, defined glycans for
functional studies critical for advancing glycomics; e.g, mgs of pure human milk oligosaccharides (HMO),
available since the 1950’s supported research that led to our understanding of the benefits of HMO in breasfed
infants, resulting in infant formula manufacturers introducing HMO into their products in 2014, based on clinical
trials supporting their efficacy. Mammalian glycans,on the other hand, expressed on the surfaces of all cells, are
generally available only in minute quantities; making them as available as HMO to the research community would
rapidly advance understanding of their functions in animal cells. This is now possible using our proprietary
technology, Oxidative Release of Natural Glycans (ORNG), which chemically releases glycans from
glycoconjugates of any natural material using household bleach. NatGlycan, LLC (NGC) was established to
provide biologically relevant natural glycans reliably, economically, and in large quantities. In Phase I we
demonstrated the feasibility of producing high mannose N-glycans in mg quantities for sale to the glycoscience
community for the first time. We believe the economy of scale will support reasonable prices. Sigma-Aldrich sells
20µg of Man9GlcNAc2 for $688, while NGC is selling 5 mg of Man9GlcNAc2-AEAB for $750. In Phase II of this
project we will complete a manufacturing facility to produce 100’s of mg (purity >95%) of all high mannose N-
glycans and derivatives that will be useful to the glycobiology community. In addition, we plan to launch highly
purified N-glycans representing all of the structures expressed on human and recombinant IgG for use as QC
standards in mAb manufacturing; currently an unmet need in the pharmaceutical industry. Since ORNG releases
all classes of glycans simultaneously from natural products, we will rapidly expand our product offerings. We will
purify the major O-glycans that are in great demand, but not currently available at reasonable cost. We anticipate
that by the end of Phase II, we will be offering hundreds of N-glycans and O-glycans (purity...
