Tony,
As Ed said, DDM is not, nor will ever be cheap. However, the Anatrace
sol-grade is primarily for the early stages of a protein's isolation
and purification, but is not recommended (or intended) for
crystallization or biophysical experiments. Use their purer grade for
the latter.
What do you mean "large quantities" of DDM? If you need a lot of DDM,
Anatrace is always happy to quote you lower prices for larger bulk
orders. They have been always eager to help.
If you find cheaper sources, ALWAYS make sure there is no batch to
batch variations in quality (I have seen a batch of insoluble octyl
glucoside from a very reputable German firm!!!). Run CMC measurements
and TLC on all new batches and ALWAYS keep a bit of the old batch when
you shift over to a new batch. It will save you many days of headaches.
Good luck,
Michael

You get what you pay for, and this is not a cheap detergent!
If your application is not sensitive to a little bit of the alpha-
anomer,
try Anatrace sol-grade, 25 g for $803.01:

If you find something cheaper, I'd like to know.
