      Storage -20°C
      Storage Conditions FTC-casein should be stored at -20°C and is stable for one year from the date of purchase. FTC-casein stored at 4°C is stable for 2-3 days. Several freeze-thaw cycles will lead to a minor increase in the background fluorescence, so following initial thawing, we suggest that this reagent be divided into 5 aliquots. FTC-casein is light sensitive and should be protected from light.
      Protease positive control should be stored at -20°C. As with many proteases, trypsin is susceptible to autolysis and you may notice a reduction in trypsin activity with time, even if stored at -20°C.
      Incubation buffer and assay buffer may be stored at 4°C or -20°C.
