Abstract: The intention of this paper is to utilize the simultaneous staining technique on same slab gel of PAGE to analyse superoxide dismutase (SOD)and lactate dehydrogenase (LDH ) isozymes in the plasma from three species of Murids．We also used PAGE to analyse the plasma proteins．The result obtained is satisfactory．The isozyme bands
of SOD were colorless and transparent and their migration rates were faster，whie the isozyme bands of LDH were stained and their migration rates were slower．In the Plasma of each species the number and the mobility of SOD and LDH isozymes were different，thus the isozyme patterns of each species possessed their special characteristics．In addition，the electrophoretograms of the plasma proteins also had different features from this species to that species．For instance，the number and the mobility of prealbumin and transferrin bands were different in various species analysed．These differences mentioned above can usually be attributed to differences of species．It is evidently showed that the technique of simultaneous staining is convenient and effective for study on SOD and LDH isozymes simultaneously．
