Purpose and BackgroundsCHO lec 3.2.8.1 cellsCHO Lec 3.2.8.1 cells have four independent mutations in the N- and O- glycosylation pathways (Stanley, 1989). N-linked carbohydrates produced by CHO Lec 3.2.8.1 cells are all of the high mannose type, but differ in the number of mannoses, ranging from Man9 to Man5. O-glycosylation is homogenous, with only a single GalNAc residue attached per site. When cultured in the......阅读全文
