AG924005: β-D-Lac-Ethyl-Azide (Peracetate) Pack Size:100 mg / Fmoc-Tyr(Gal(Ac)4-β-D)-OH / Fmoc-L-Tyr(Gal(Ac)4-β-D)-OH

/ Fmoc-Tyr(Gal(Ac)4-β-D)-OH / Fmoc-L-Tyr(Gal(Ac)4-β-D)-OH

The installed glycan is an L-rhamnose residue

4-Methylumbelliferyl (MU) glycosides are fluorogenic enzyme substrates: cleavage of the glycosidic bond by the target enzyme releases free 4-methylumbelliferone

22 / An α-D-galactose ligand equipped with an azide-functionalized linker through a short ethyl spacer

α2-3 sialosides are ligands for selectins and certain Siglecs

AG924005: β-D-Lac-Ethyl-Azide (Peracetate) Pack Size:100 mg / Fmoc-Tyr(Gal(Ac)4-β-D)-OH / Fmoc-L-Tyr(Gal(Ac)4-β-D)-OHC28H39N3O18 705. 6 A peracetylated D lactose ligand equipped with an azide functionalized linker through a short ethyl spacer. The terminal azide can be covalently coupled to alkyne partners via copper catalyzed azide alkyne cycloaddition (CuAAC), or to dibenzocyclooctyne (DBCO) and related strained alkynes using copper free click chemistry, forming stable 1,2,3 triazole linkages. The sugar hydroxyl groups are protected as acetate esters (peracetate);
