Metabolic glycan labeling (MGL) has been employed for diverse purposes, such as cell surface glycan imaging and tumor surface engineering. We herein reported organelle-specific MGL (OMGL) for selective tagging of the inner limiting membrane of lysosomes over the cell surface. This is operated via acidity-promoted accumulation of optical probes in lysosomes and bioorthogonal ligation of the trapped probes with 9-azidosialic acid (AzSia) metabolically installed on lysosomal membrane proteins. Overcoming the limitation of class
