Does anyone out there have any experience staininig for Hyaluronic
     Acid Binding Protein or proteoglycans in general?
     I have been trying to stain (human) skin for a panel of proteoglycans
     and HABP is the latest request. The protocol that I have from
     Seikagaku uses a 2 hour incubation in Sigma chondroinase for
     "unmasking" and digestion in hyaluronidase for the negative control.
     Another journal paper that I have doesn't use the chondroitinase step
     at all. I am using formalin-fixed, paraffin sections and have had
     mixed results with the other proteoglycans so far.
     Any tips would be greatly appreciated.
