The method that seems to work best for us involves the use of CNBr-activated
Sepharose 4B beads from Pharmacia catalog number 17-0430-01.  This is a simple
procedure and it has worked well in coupling both IgG and IgM abs.  Pharmacia
also states in their catalog that this is the "method of choice for
immobilizing Ab".  They also have a nice protocol/package insert that explains
the procedure.  Good luck.he
