Regarding shelf life of Cleland's Reagent (DTT to you youngsters), if in an
unopened ampuole or original sealed container it should be good for a number of
 years if not subjected to high temperatures.  I have used DTT that was kept
for about 10 years at 6 degrees (as dry crystals) with good results.  It will
go to pot rapidly if exposed to air.
