Peter -

Agreed, glyco stuff can be 'floppy', and increase friction. However, in the
present case, given that the mass estimated by SLS (41.4 kD) agrees well
with (what I take to be) the formula weight (41.7 kD), it is not too likely
to be an explanation, is it ?

Ewa and Arthur,
there's also a possibility that the frictional ratio could be quite high if
the protein is glycosylated.  In my experience, that can increase the
friction quite a bit.
