Fifteen samples of cis AB bloods belonging to six unrelated families were tested by serological and thermodynamic assay techniques. The B and H antigens of cis AB bloods differ significantly from those of trans AB bloods. Differences were found among unrelated samples, but identical results were obtained within a given family : this could mean that there had been as many mutations as there were families.
