title: Acquired B antigen disappearance by in vitro acetylation associated with A1 activity restoration.
abstract: The chemical acetylation of RBC bearing the acquired B antigen led to the disappearance of the agglutinability by anti-B and restored the A1 specificity. The same results are obtained using RBC transformed in vitro by a Clostridium Tertium filtrate, where a deacetylase was reported.
