Ketone-modified CMP-Sia is transferred by ST6GalNAc1 for selective tagging, followed by reversible oxime capture using hydroxylamine beads. Mild acid release enables tag-free recovery and quantitative assessment of sialylation occupancy on core GalNAc residues in complex samples.","dates":{"publication":"Wed Mar 04 00:00:00 GMT 2026"},"accession":"PXD075239","cross_references":{"TAXONOMY":["9606"]}}
