Prot. A Sepharose-Regeneration

[Dr. Christian Klaus]

I am using Protein A Sepharose (Pharmacia)  for immune precipitations. I
elute immune complexes after binding with laemmli buffer (SDS-PAGE
loading buffer). 
Is there anyone who has experience, whether this very expensive material
can be regenerated and  reused. I would be glad if some netter had a
protocol for me.

Thanks in advance
