Isoenzymes of alkaline phosphatase in serum of lambs and ewes.
Electrophoresis in polyacrylamide gels was used to identify isoenzymes of serum alkaline phosphatase in sheep. Skeletal isoenzyme predominated in the serum of lambs and liver, skeletal and intestinal isoenzymes were found in the serum of adult ewes. In r ewes (R-r-i blood group system) intestinal isoenzyme activity was 67 per cent of total serum activity; in R ewes intestinal activity was only 36 per cent of total activity. Relative activities of the three isoenzymes differed greatly within individual ewes and between individual ewes during pregnancy and lactation.
