Hi,

We would like to know if the DTT (Dithiothreitol) from Fisher (BP172-25) is
good to make buffers for large scale protein purification. With our discount
we can get 25g for about $150.00. However, the chemical is not tested for
RNAses, DNAses, and proteases. Sigma's DTT is free of all these nasties, but
more expensive. Are there other cheap sources for good quality DTT? Thanks a
lot!

Chris
