The structures of the N-linked oligosaccharides in glycoproteins synthesized by mouse teratocarcinoma F9 cells and retinoic acid differentiated F9 cells have been investigated. F9 cells and retinoic acid differentiated F9 (RA/F9) cells were incubated in media containing either (2-{sup 3}H)mannose, (6-{sup 3}H) glucosamine for 24 hr to radiolabel metabolically the oligosaccharide moieties of newly synthesized glycoproteins. Analyses of the radiolabeled glycoproteins by sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS/PAGE) and fluorography demonstrated that numerous glycoproteins from both cells were labeled by all three radioactive sugar precursors. Oligosaccharides were prepared from total-radiolabeled glycoproteins and analyzed by a variety of techniques. The transferrin receptor has been purified from both F9 and RA/F9 cells. The structures of N-linked oligosaccharides in the receptor were high mannose and complex-type.
