It is designed for high-resolution and high-throughput analysis with unique selectivity for biologically important glycans, either labeled or native, by LC-fluorescence and LC-mass spectrometry (MS) methods.The GlycanPac AXH-1 column can be used for qualitative, quantitative, and structural characterization of uncharged and charged glycans present in biological molecules (e.g., proteins).Features:Unique glycan selectivity based on charge, size, and polarityExcellent resolution for both native and labeled glycansUseful for both high-resolution glycan profile characterization and easy quantification of glycans based on chargeCompatible with fluorescence and MS detection methodsHigh chromatographic efficiency and excellent column stabilityThe GlycanPac AXH-1 column, based on innovative mixed-mode surface chemistry, combines both weak anion-exchange (WAX) and hydrophilic interaction liquid chromatography (HILIC) retention mechanisms for optimal selectivity and resolution power. The WAX functionality provides retention and selectivity for negatively charged glycans, while the HILIC mode facilitates the separation of glycans of the same charge according to their polarity and size. As a result, the GlycanPac AXH-1 column provides unparalleled capabilities for glycan separations. Additionally, this column offers charge-based separations for various glycans without discrimination of size and polarity, making it a suitable tool for accurate quantification of glycans which cannot be achieved with other HPLC columns. The GlycanPac AXH-1 column is designed and tested for LC-fluorescence detection and LC-MS applications using volatile aqueous buffers (e.g., ammonium acetate or ammonium formate) and acetonitrile.GlycanPac AXH-1 columns are based on high-purity and spherical silica substrates in both 1.9 and 3 μm sizes for UHPLC and standard HPLC applications, respectively. GlycanPac AXH-1 columns are available in various dimensions for applications with different resolutions, throughput, and instrument requirements.The GlycanPac AXH-1 column can be used for qualitative, quantitative, and structural characterization of uncharged and charged glycans present in biological molecules. The glycan elution profile consists of a series of peaks grouped into several "clusters" in which the neutral glycans elute first, followed by mono-sialylated, di-sialylated, tri-sialylaled species.Analytes in each cluster, retained by anion exchange interactions, represents the glycans of the same charge. Within each cluster the glycans having the same charge are further separated according to their sizes and polarity by HILIC interaction.Similar separation of N-glycans using a 3μm packing material with Fluorescence detection.Separation of N-glycans using the GlycanPac AXH-1, 1.9μm packing with LC/MS detection.Accurate and easy quantitative analysis of relative amounts of glycans of each charge state is possible by using a modified gradient.Separation of human IgG using the GlycanPac AXH-1, 1.9μm column.Analytical ColumnsGlycanPac AXH-1, 3 μm, Analytical (4.6x150mm)082468GlycanPac AXH-1, 3 μm, Analytical (3.0x150mm)082469GlycanPac AXH-1, 3 μm, Analytical (2.1x150mm)082470GlycanPac AXH-1, 1.9 μm, Analytical (2.1x250mm)082521GlycanPac AXH-1, 1.9 μm, Analytical (2.1x150mm)082472GlycanPac AXH-1, 1.9 μm, Analytical (2.1x100mm)082473GlycanPac AXH-1, 1.9 μm, Analytical (1.0 × 150 mm, with nanoViper)164863Guard ColumnsGlycanPac AXH-1, 3 μm, Guard (4.6x10 mm) 2ea (Use Holder V-2)082474GlycanPac AXH-1, 3 μm, Guard (3.0x10 mm) 2ea (Use Holder V-2)082475GlycanPac AXH-1, 3 μm, Guard (2.1x10 mm) 2ea (Use Holder V-2)082476Acclaim SST Guard Cartridge Holder V-2069580Acclaim Guard Kit (Holder and coupler) V-2069707Guard to Analytical Column Coupler V-2074188DataSheetGlycanPac AXH-1 ColumnBrochuresThermo Scientific BioLC ColumnsManualsThermo Scientific GlycanPac AXH-1 Columns Product ManualGLYCANPAC AXH-1 COLUMN Quick StartPostersNovel Glycan Column Technology for the LC-MS Analysis of Labeled and Native N-Glycans Released from Proteins and Antibodies
