PLASMA-PROTEIN POLYMORPHISMS IN THE TAMMAR WALLABY, MACROPUS-EUGENII

Five populations of the Australian tammar wallaby, Macropus eugenii, f rom Kangaroo Island, South Australia, and Garden, Abrolhos and Middle Islands and Perup, Western Australia, were examined for plasma protein polymorphisms. Select Kangaroo/Garden Island hybrids and backcross pr ogeny were also included in the study. Vitamin D binding protein (GC), albumin (ALB), transferrin (TF), protease inhibitor (PI), haemopexin (HX), haptoglobin (HP) and immunoglobulin G (IgG) were identified by p olyacrylamide gel electrophoresis, pH 7.9, isoelectric focusing, pH 4. 2-4.9, and immunoblotting with rabbit antisera to human proteins. Five GC (A, B, C, D, E), two ALE (A, B), two TF (A, B) and five PI (I, J, L, M, P) variants were detected, and limited family studies demonstrat ed a codominant allelic inheritance for each of the systems.
