Hi Jacob,

I am not sure I understand why a spread in pricing indicates illegal
activity.
Wouldn't uniformly high prices indicate something illegal, and very
different
prices just indicate you have a choice of suppliers, qualities etc?!?

And just to mention two more supplier names (again: different brands,
different
prices) for IPTG we never had problems with:

Applichem, current promotion price 155 Euro for 25 g

Roche, promotion starting Aug (according to a Roche sales person) 128 Euro
for 5 g

Best
Clemens
