RE:frozen antibodies

From:louise renton

Hi Deb,
I find that this is the best way to go,  freezing 10ul of antibody in small 
microcentrifuge tubes. We invested in a 'step' pipette to assist us and this 
limited repetitive strain on the thumbs!! HOWEVER there were some antibodies 
that did not take kindly to this treatment and unfortunately since I no 
longer work with them, I cannot remember which they were. Give it a whirl 
with a small sample of your ab and see if it has an adverse effect. We also 
froze left over diluted ab from the day's run. These were thawed and used 
only once before discarding. It made some small savings to the budget.

Best Regards
