Ed,

I am not sure how different the product might be from that of BDH Chemical, 
however, BioRad Labs does sell HA that is used in binding nucleic acids.  You 
can also prepare your own HA (see Lachance, M.  1980.  IJSB. vol. 30. pgs 
433-436).

Again the HA that is prepared is used bind nucleic acids.  BTW, I have 
compareds the "homemade" HA with the commerical HA, and have not found a 
difference in their performance.

I hope this helps.
