The GlycanAssure HyPerformance APTS Kit is an N‑glycan rapid‑release, labeling, and cleanup kit that offers an N-glycan sample prep workflow for high-throughput glycan characterization applications within biopharma. Combined with the Applied Biosystems 3500xL Genetic Analyzer or Thermo Scientific Vanquish UHPLC system, the GlycanAssure HyPerformance APTS Kit offers an end-to-end N-glycan analysis solution, from clone selection to lot release.
Key features include: • Easy N-glycan sample prep workflow for both LC & CE analysis platforms • Superior data quality with unparalleled robustness • Proprietary denaturant delivering complete deglycosylation of glycoproteins • Preservation of sialylation offering accurate quantitation of sialylated glycans • High-throughput end-to-end N-glycan analysis significantly reducing time to results
Workflow Glycosylation is one of the key critical quality attributes of glycoprotein (mAb)-based biotherapeutics. Current glycan analysis methods consist of labor-intensive sample preparation that involve the use of toxic reagents, time-consuming vacuum centrifugation steps, and multiple pipetting steps.
The GlycanAssure HyPerformance APTS workflow overcomes these limitations. It delivers complete deglocosylation using a proprietary denaturant and superior preservation of sialylation, an important quality attribute of glycoproteins. Accurate quantitation of sialylated glycans is critical in biosimilar development. Most common sample prep methods cause de-sialylation of the glycans, leading to inaccurate quantitation. In addition, LC based separation techniques poorly quantitate highly sialylated glycans because they elute at the end of the LC profile. The GlycanAssure HyPerformance kit offers excellent preservation of sialylated glycans and allows analysis on a CE instrument where highly sialylated glycans migrate at the beginning of the electropherogram, enabling accurate quantitation.
The released, labelled glycans can be analyzed with either the Applied BioSystems 3500xL Genetic Analyzer for Protein Quality Analysis for high throughput applications or Thermo Scientific Vanquish Flex UHPLC System for lower throughput applications, for an end-to-end glycan analysis solution from Thermo Fisher Scientific.
Kit description The GlycanAssure HyPerformance APTS Kit is part of the GlycanAssure Glycan Analysis and Quantitation System and contains all reagents and buffers needed to analyze and quantitate N-glycans from glycoprotein samples. APTS is a traditional dye used for glycan labeling and the labeled glycans can be analyzed using capillary electrophoresis (CE) or liquid chromatography (LC) systems. The GlycanAssure sample preparation workflow is a streamlined, automatable method for the processing and analysis of 96 glycoprotein samples in ~5 hrs.
