I agree, great idea.

Many antibodies can most definitely be used after their expiration 
date. Case in point, I recently used an anti-CD31 antibody clone 
MEC13.3 from RDI which was probably 5 years old - way past it's 
expiry date - and it worked as beautifully on my acetone fixed 
frozens as it did on the day I got it. It had been stored (as all my 
antibodies are) at 4 deg C.

So this won't be the case for all of them, but certainly many can 
still be used.
