HiTrap Protein A columns reuse

Dear Student
We use HiTrap Protein G columns (and HiTrapNHS-mAb columns also) and they seem 
to last and last.  We have had only one column fail in ~6 years, which was a 
Protein G column used to purify mouse asites antibody.  As long as the serum 
is clean (lipids can kill any column quickly) a HiTrap column use by date can 
be regarded as a long time!  We have had a HiTrapNHS-anti ovine IgE mAb column 
 still working well after in excess of 500x pH 3.0 Glycine elutions. Actually 
you are more likely to lose a column by dropping it and breaking the end off.
