BSA is not particularly good as a blocking agent (milk powder of fish skin  
gelatin are good), so feel free to find other uses for it ;-)

Bacteria will use the amino acids contained in this protein. I would  
normally consider BSA too expensive for that purpose (trypton is commonly  
used) but since you have some around...
