Blood protein polymorphism in donkeys (Equus asinus) in Morocco

Abstract

Albumin (ALB), vitamin D-binding protein (CC), Alphal-B  glycoprotein (Al B) and transferrin (TF) polymorphisms were  studied in 170 Moroccan donkeys by polyacrylamide gel  electrophoresis (PAGE). Two variants, already described in  the literature, were detected using the ALB and CC systems.  Two new Al B variants, called Al B-A and Al B-D*, were  found. An additional TF variant, designated TF-A*, was also  observed. The Al B-A variant migrated more positively than  that of Al B-D*, but each one was faster than the Al B-D type.  Furthermore, the TF-A* variant migrated more positively than  the TF-A type.
