Your message to the net parallels some work I am doing.  I am in the 
process of having antibodies raised in chicken and found a method for the 
purification of Ig"s .  Look in volume 2 of Cell Biology (Academic, 
press-1994).  The article is by Kokko et al., p282-288.  It contains a 
fairly complete discription of Ig purification including buffer systems. 
If you don"t have access to these protocol sent me an email and I will 
FAX it to you.   The literature citation at the end of the chapter will 
be very useful.

I would like to keep in touch to see how your affinity column works out.

PS -- the system I'm working with are synthetic peptides to plant derived
