I made a stock solution of palmitate in 50% ethanol and I keep it in -30 degrees. Every time I use it for treatment of my cells I find the palmitate reprecipitating in stock. So I reheat the stock solution does this affect the stability of palmitate?

Asked by: DinaMostafa
Thank you for your question. We always recommend to use stock solutions the same day they are made. However, if you need to make and freeze, we recommend aliquoting the stock solution out prior to freezing. The number of freeze/thaw cycles should be minimized as this can affect the stability.
