Long term storage of bacteria in fetal calf serum -70 or -80
Posted 23 August 2010 - 09:47 PM
May I ask which temperature is most optimal for keep bacteria in fetal calf serum. -70 or -80? I did observe the usual temperature for storage of bacteria is -70 degree celcius... But due to the original factory setting in my freezer I have been using -80 for a long time. I am paranoid whether this is acceptable or whether this will have any effects on my isolates??
Have a good day =)

That would not be different between -70 or -80. I think glycerol is needed in the preservation of bacteria.
