Possibly not. DAS has a low solubility (3% or 3g / 100ml of water at room temperature). Refrigerating the solution will drive some of that out of solution. You'll have to make sure that it comes back up to room temperature and that everything is re-dissolved before use. That's hard to do while mnimizing exposure to light, IMO.

It is probably best to plan on storing this as a dry powder.
