We have used a Pierce kit but substituted Pharmacia Sepharose Protein G, as
our mAbs don't bind to Protein A. The system worked OK. See the paper
Schneider et al, 1982, The J. of Biological Chemistry, v257, n 18, pp 10766,
as many of these kits are based on this paper. See also Harlow and Lane,
Antibodies; A Lab Manual.
Make sure that the antigen preparation you are going to use contains no
antibodies that bind Protein A (or G) as these will bind to unfilled sites.
These columns leak only minimal amounts of antibody.
