EXPIRED ANTIBODIES FOR FLOW

Dear Margaret:

Unfortunately my experience has been incredibly varied.  I have seen 
antibodies that had been expired for years work wonderfully and have 
seen antibodies that are recently expired work poorly.	I think you 
really have to test the antibodies and have non expired controls to 
compare them too. I also think that lots of times it is the 
flourochrome that has diminished, not the antibody binding.

Sorry I can't be more help.

Janet
