protocol for immunobeads

[SPAGNOL at PLAUTO.CSATA.IT]

Dear Sirs, I'm sorry for repeating myself
but something should have gone wrong when I was sending the 
message the first time:does anyone k
w a protocol
 for using Bio-Rad's
antibody-coupled polyacrilamide immunobeads 
for immuno-precipitation?
I found a bunch left in my Lab, but no protocol.
Thanks in advance.
Sincerely,
