is beta-galactosidase a glycoprotein?

[Justin Kemp]

I am looking for a high molecular weight protein above 100 kDa (excl.
myosin heavy chain or phosphorylase B) to act as a negative marker for a
glycoprotein stain. I have been told that beta-galactosidase may be
suitable. Can anyone tell me if it is indeed devoid of carbohydrate? 
Any help much appreciated,
Justin (PhD student).
