text: It has now surprisingly been found that IgG of high purity (e.g. complying with the European Pharmacopoeia monograph 0338 for normal immunoglobulin comprising not less than 85 wt.% monomer and dimer and not more than 10 wt.% polymer and/or aggregate) can be relatively easily obtained from precipitate fractions which were previously considered as "waste" fractions during plasma fractionation processes to produce IgG, without the need for chromatography steps, and particularly without the need for affinity or anion exchange chromatography steps.
