Dear all,

I stained a gel with PAS(periodic acid stain) method for visualizing
However, even protein markers and the reconstructed protein expressed
by E. coli could be stained.
Whether the PAS method is specific for visualizing glycoproteins?
And how to explain the non-glycoprotein can also be stained?

I am appreciated of any help of you!
