Hi Pfaust, I think I can help you clean up your Ab prep but I need some
more Info What is the source of the Ab? What have you used to get to
87%? What are the major contaminants? What M.W.? What resins/equipment
do you have available? Will this prep be used in a therapeutic
application?
I'll be glad to help get you to 95%. Let me know.
