Abstract
The disclosure relates to labeling glycans and glycosphingolipids from undefined mixtures with chemical moieties that emit light when exposed to electromagnetic radiation and uses of these labeled glycans and glycosphingolipids in microarrays for research and diagnostic purposes. In certain embodiments, the disclosure relates to derivatizing glycosphingolipids with a marker.
Claims7
A glycosphingolipid comprising a moiety of formula I:
- or salts thereof wherein n is 2, 4, 8 or greater.
A purified tagged glycosphingolipid of formula II,
- or salts thereof, wherein n is 2, 4, or greater than 4, m is greater than 4, 9, 12, or greater than 13, and Gly is a glycan.
A tagged glycosphingolipid conjugated to a solid surface wherein the tagged glycosphingolipid comprises a moiety of formula I:
- or salts thereof wherein n is 2, 4, 8 or greater.
A solid surface comprising a plurality of zones wherein the zones comprise purified tagged glycosphingolipids or purified tagged glycans conjugated to the surface provided that at least one of the zones comprises tagged glycosphingolipids and wherein the tagged glycosphingolipid comprises a moiety of formula I:
- or salts thereof wherein n is 2, 4, 8 or greater.
