What are your antibody stability testing practices?

We test all unconjugated antibodies for 1 week (7 days) at -20C, room temperature (ambient) and 37C, then assess each stability test sample by western blot compared to the -20C stock. If there is no change in the performance of the antibody at room temperature or 37C by western blot after the 1 week period, the antibody is considered stable and shipped at ambient temperature without ice packs. If the antibody performance changes in any way after this time period, the antibody will be shipped cold with ice packs. Please note that regardless of the shipping method, the antibody should be stored at -20C upon arrival.
