Dear Anne
I would recommend affinity purification:
Immobilise the purified protein on a column e.g.: HiTrap-NHS activated
from Pharamacia, centrifuge the serum , dilute it 1:20 with PBS apply
it onto the column and do an acidic elution with Glycine/HCl pH=2.7-
afterwards the eluate has to be neutralised.
Good luck Martin
