Neutral loss scan by TIM for detection of sulfated glycans. N-Glycans, GSLs, and O-glycans were analyzed by TIM, and the resulting TIM data were filtered for neutral loss of a sulfate group to identify sulfated glycans. Significant MS signals consistent with sulfation were only detected on glycans released by reductive β-elimination, demonstrating that glycan sulfation is most abundantly presented on O-glycans. The TIM profile for sulfated O-glycans harvested from a representative analysis of bovine oviduct epithelial cells is shown.
