APPβ generated in the presence of BFA is partially glycosylated. Cultures of NT2N neurons were metabolically labeled as in Fig. 7 in the presence or absence of 20 μg/ml BFA. The cell lysates were then immunoprecipitated with the antibody 53. (A) Samples in lanes 3 and 4 were treated with Nglyc F for 16 h to remove N-linked sugars, whereas immunoprecipitates in lanes 1 and 2 were treated with the vehicle. (B) Samples in lanes 2 and 4 were deglycosylated with a combination of Nglyc F, neuraminidase, and O-glycosidase for 16 h to remove both N- and O-linked chains (lanes 2 and 4); lanes 1 and 3 represent samples that were mock digested.
