Hi Steve:

    Albumin is a very large protein that is largely confined to the=20
vascular system. Yes, it is made in hepatocytes but I suspect that it=20
diffuses quickly in sections. Also, the form that exists inside cells=20
may not react with your marker? I suspect that freeze drying or freeze 
substitution might (emphasis on might) be the way to go here. Also, a=20
PubMed or Medline search will reach a much larger database than Histonet 
and you might find the methods you seek.
