   Recently, when I tried to order that item, I was informed that
Sigma had deleted it and was offering another detergent (5ml free
to test it).  It was not made clear to me that this was the chemical 
equivalent of NP-40, and I did not have the time to test it at the
bench.  Therefore, I obtained the known stuff from Calbiochem.  If
any netters have tested the Sigma prep, please post as I'd like to
know if it is suitable.
