Reusing Nucleobond cartridges

[peter at chempath.uct.ac.za]

Some time ago I came across a web site describing the reuse of Nucleobond AX 
DNA purification columns. Unfortunately I lost the details of the address. 
Could anyone here supply me with that address? Also, has anyone tried this 
protocol and what is the general consensus of its affectiveness? As I 
recall, the protocol involved washing the column with dH2O after the normal 
elution step and then either re-equilibrating with buffer N2 for immediate 
reuse or washing again with 50% EtOH and storing at 4C.

Thanks in advance for any assistance.
