Endoglycosidase digestions of sVSG221 from wild type and TbUAP
conditional null mutant cells. A, sVSG221 purified from wild type
and TbUAP conditional null mutant (TbUAP cKO) cells before
(0 h) and after 48 h without tetracycline (48 h) were subjected to SDS-PAGE
and Coomassie Blue staining. B, aliquots of wild type sVSG221 were
digested with Endo H (that removes only oligomannose N-linked
glycans) or PNGase F (that removes all N-linked glycans), and the
products were subjected to SDS-PAGE and Coomassie Blue staining. Species
containing two, one, and no N-linked glycans were resolved, as
indicated. C, aliquots of sVSG221 from TbUAP conditional
null cells grown for 48 h without tetracycline were digested with Endo H or
PNGase F, and the products were subjected to SDS-PAGE and Coomassie Blue
staining. Species containing two, one, and no N-linked glycans were
resolved, as indicated.
