Abstract1.1.|Horse and donkey serum esterases were compared using histochemical and immunological criteria in starch and agar gel electrophoresis, immunoelectrophoresis and immunodiffusion.2.2.|One out of several lipoprotein esterases shared by the two species, designated α-ϱ esterase owing to its variable migration rate in agar electrophoresis, migrates faster than albumin in agar but slower in starch. The antigen-antibody complex formed with either homologous or heterologous antibodies is enzymatically active; it hydrolyzesβ-but not α-naphthyl acetates. These esterases are antigenically identical in horse and donkey; the corresponding antibodies are present in both anti-horse and anti-donkey rabbit antisera.3.3.|A non-lipoprotein esterase of α1 location is found in horse sera exclusively. It migrates slower than albumin in agar and in starch; the antigen-antibody complex is enzymatically active, and it hydrolyzes both α- and β-naphthyl acetates. The corresponding antibodies are present only in anti-horse antisera, rabbit or donkey.
