Cell labeling agent and cell labeling kit

Abstract

The cell labeling agent includes a monosaccharide derivatives with a six-membered ring structure that are metabolized to sialic acid in the sialic acid biosynthetic pathway of cells. Among the groups bonded to carbon atoms constituting a six-membered ring in the monosaccharide derivatives, at least one group that does not change, even when metabolized by the sialic acid biosynthetic pathway, includes a ring structure with a carbon-carbon double bond or triple bond.

Dependencies are inferred from the claim text.
