Complex N-Linked Oligosaccharides

Most of our N-linked oligosaccharides are isolated from proteins from cell culture supernatants of CHO cells or BHK cells. The structures have core ?1-6 fucose and ?2-3 -linked NeuAc and are available with and without N-acetyllactosamine repeats. They are destined to be used as reference standards in quality control release tests of pharmaceutical glycoproteins by glycosylation mapping procedures (HPAEC-PAD, mass spectrometry and others). The underlying fully sialylated structures are analyzed by NMR, ESI-MS and MALDI/TOF-MS and are quantified by using two validated HPAEC-PAD methods.
