It is common practice to maintain samples frozen at -80 degrees C for medium to long-term storage. For proteins, sera, etc. this temperature is often preferred over -20 degrees C. Does anyone know of any studies that demonstrate differences in protein stability for long-term storage at these temperatures? I'm looking for a few good papers on the topic.
Thanks Joshua. A very good service to all experimental workers in the field. Thanks again.
You can freeze protein by immerse sample in liquid nitrogen or Co2

Thanks, Joshua! It struck me as odd that what everyone commonly understands is sometimes so poorly referenced!
