This high-purity N-glycan reference standard is designed for accurate identification and quantitation of complex N-glycans featuring terminal α(2,6)-linked sialic acids. Each vial contains a well-characterized synthetic glycan with an AdvanceBio InstantAB label, enabling optimal fluorescence and mass spectrometric detection. Researchers rely on this standard for system suitability assessment, method validation, and calibration of glycan profiling workflows in biopharmaceutical development and quality control. Suitable for use with Agilent AdvanceBio Glycan Mapping columns, 1260 Infinity II and 1290 Infinity II LC systems, as well as Q-TOF mass spectrometers, it ensures confidence in structural assignments during glycoprotein analysis. Compatible with a broad range of sample preparation protocols and analytical platforms, this standard is an essential tool for laboratories performing glycomic or glycoproteomic characterization. It helps streamline development of robust HILIC-FLD or LC-MS workflows and supports regulatory compliance for therapeutic glycoprotein characterization. When used alongside other glycan standards and ladders available from Agilent, it enables comprehensive assay performance verification and comparability studies. This product aids researchers in detailed structural elucidation, lot-to-lot consistency checks, and monitoring of sialylation patterns, contributing to more accurate and reproducible glycan analysis.
