Has anybody tried the chloroform/PEG method of antibody purification
from egg yolk?  Do these antibodies perform well?  The method (Polson,
1990, J Imm Inv) is easy and gives good yields but the original
article uses an Ouchterlony assay as the only proof of Ig function --
I'm a little concerned about possible effects of chloroform on the Abs
performance in sandwich assays.
I'd appreciate any feedback from anyone with experience in these
