Ovalbumin high-mannose

Example The PSD-MALDI-TOF spectrum of the [M+Na]" ion, m/z 1418.9, of high-mannose A-linked glycan (Man)6(GlcNAc)2 from chicken ovalbumin recorded from DHB shows distinct cleavages of the branched carbohydrate skeleton (Fig. 10.16). [134]... 

Figure 1.3 Examples of High Mannose Structures in Glycoproteins. Of the examples shown (M) and (M)g have been found in the membranes of Chinese hamster ovary (CHO) cells and the remainder in ovalbumin. Several other glycoproteins are known to carry closely related structures, in which the arrangement of mannosyl residues is strongly conserved (see Tai et at., 1975 Li and Komfeld, 1979). Monoglucosylated forms of (M)9, (M)g and (M)7 are now known (Mellis and Baenziger, 1983).
