Tetrasialylated, (2-3 linked) tetraantennary plus proximal alpha 1-6 Fucose

Tetra-antennary complex type.

Most of our N-linked glycan standards are isolated from cell culture supernatants of CHO cells or BHK cells. The structures have core alpha 1-6 Fucose and alpha 2-3 linked NeuAc and are available with and without N-Acetyllactosamine repeats. They are used as reference standards in quality control release tests of pharmaceutical glycoproteins by glycosylation mapping procedures such as HPAEC-P, HJPLC, UPLC and MS. The underlying fully sialylated structures are analysed by NMR, ESI-MS and Maldi/Tof-MS. We can supply quantified standards by using two validated HPAEC-PAD methods on request.
