Dimeric Definition & Meaning - Merriam-Webster

WebThe dimeric IgG fraction is thought to represent mainly idiotype-antiidiotype Ab pairs. Treatment of all IgG fractions at pH 4 effectively monomerizes the IgG dimers resulting in separated idiotype-antiidiotype Ab pairs and thus in a comparable F (ab') (2) binding site availability of the different IgG fractions.
