Abstract
The presence of TeBG in a variety of higher vertebrate species was investigated by an (NH4)2SO4 precipitation technique. TeBG was demonstrated in significant amounts in primates, carnivora, marsupiala and some artiodactyla, even in circumstances where previously electrophoretic studies failed to identify it. TeBG was also shown in trace amounts in certain rodents and birds. TeBG in the kangaroo substantiates the primitiveness of the protein in the mammal line and its absence in certain orders and species of eutherian mammals must represent a secondary loss.
