WebDo not store glycerol-containing antibodies at -80 °C. Unless a stabilizing protein, such as BSA (1% w/v), has been added, antibodies should not be stored for extended periods at their working dilutions. Avoid storing diluted antibodies for extended periods. The major problem encountered during storage is contamination with bacteria or fungi. WebProtein storage at -20ºC usually requires the addition of 50% glycerol to your sample to avoid freezing at this temperature. If we plan to store a protein at -20ºC, we generally run the final size exclusion chromatography step in 2x storage buffer and then dilute the sample 1:1 with 100% glycerol.
