 I have a DNA extraction method that calls for Nonidet P-40 as the lysing

Does anyone have a source or catalog number for this detergent.

We regularly use NP-40 as a detergent in making extracts from cells and 
in our hands substituting Triton X100 didn't work. ICN and BDH still sell 
NP40 though.
