A2F 2-AA 聚糖
|产品名称||A2F 2-AA 聚糖|
|英文名称||A2F 2-AA Glycan|
|英文别名||AF2 N-linked oligosaccharide, FA2G2S2, FG2S2|
Sources A2F glycan is found on many mammalian glycoproteins including thyroglobulin, gamma globulins, and IgG. This product is typically purified from the oligosaccharide pool released from porcine thyroglobulin by hydrazinolysis using a combination of HPLC and glycosidase digestion.
Form Dry. Dried by centrifugal evaporation from an aqueous solution. Contains ammonium salt to stabilise against desialylation.
Molecular Weight 2491
Number of Samples Typically, 100 fmol to 10 pmol of the A2F 2-AA glycan can be detected, dependent on the sensitivity of the fluorometer, HPLC or mass spectrometer.
Labeling Selectivity Essentially stoichiometric labelling. One fluorophore molecule covalently bonded to each glycan.
Detection Fluorescence detection: 360 nm excitation wavelength, 425 nm emission wavelength.
Labeled glycan mixtures may be separated and analysed by a variety of HPLC (high pressure liquid chromatography) methods using HPLC columns.
Columns are an especially powerful tool for the purification and analysis of labeled oligosaccharides from complex glycan mixtures. Please contact us for advise regarding your particular application.
