Question (70924) | Anti-F4/80 antibody [CI:A3-1] (ab6640)

Go to datasheet (ab6640)


I bought ab6640 and ab7097 antibodies almost two years ago. Upon arrival I immediately aliqouted into smaller volume and kept them in -80 degree ever since. Do you think they are still okay to use?


The rule of the thumb is that a -80C stored antibody should be fine for the next 10 years. If you have any more questions regarding storage of our antibodies, please visit our storage guide at:
