Glycoconjugate synthesis monitoring by metabolic labeling [1,2,3].

The tetraacetylated N-Cyclopropeneacetyl-mannosamine (Ac4ManNCyoc) provides a non-radioactive alternative for glycoconjugate visualization. It is cell-permeable, intracellularly processed and incorporated instead of its natural monosaccharide counterpart N-Acetylmannosamine (ManNAc).[1,2,3]

The resulting Cyclopropene-functionalized glycoconjugates can subsequently be detected via Cu(I)-free Click Chemistry (TCO-Tetrazine-Ligation)[4] that offers the choice to introduce a Biotin group (via Tetrazines of Biotin) for subsequent purification tasks or to introduce fluorescent group (via Tetrazines of fluorescent dyes) for subsequent microscopic imaging.

Recommended concentration for metabolic labeling: 25-75 μM[1,2,3]. This concentration range may serve as a starting point for an individual assay set-up.
