FAQ: Is the amylose resin damaged by storage at -20°C?

When our kit arrived, it was placed at -20°C, but I see that the recommended storage temperature for the amylose resin is 4°C. The resin will freeze at -20°C but the performance of the resin is not degraded by one freeze/thaw cycle. After the ethanol is removed, the resin should be stored at 4°C to prevent damage from freezing.
