I can think of two possibilities, apart from the possibility of partial
1) The band detected by AB1 is fully glycosylated and the smear detected by AB2
is due to precursor unglycosylated or partially glycosylated molecules.
2) The smear detected by AB2 is due to molecules with increased charge e.g.
