Activated gel supports. Comments?

[Marc Goldstein]

Netters-

	I'm thinking of using affinity chromatography to purify an 
antibody out of a crude rabbit serum, and I am wondering which affinity 
supports work well for medium sized (~70 kDa) protein antigens.  I'd like 
to link the antigen to the support, and run the serum through, then elute 
the specific IgG off.  I've looked up the Pharmacia activated supports, 
and also those from Pierce.  Any comments on the utility of these or 
other activated resins, in terms of good or bad experiences, etc. would 
be appreciated.
Thanks!
