Hello,

We have been performing the NADH on muscle biopsies for quite some time now.  We have always used the premeasured NADH vials from Sigma.  They have now stopped selling these vials and only sell the reagent in powder(bulk) form.  Now we are having trouble with this stain.  Any suggestions...has anyone found an alternative source for these premeasured vials of NADH powder?

Thanks!
