Further studies on the genetic control of chicken plasma alkaline phosphatase isozyme

The effects of neuraminidase treatment on the electrophoretic pattern of alkaline phosphatase (AP) isozymes and AP activity were investigated in chicken plasma. AP comprised three isozymes. The zymogram of an individual chicken plasma had two bands, either the faster (F) or the slower (S) moving band by isozyme types and the B band irrespective of isozyme types. Mobility of the S band and AP activity in chicken plasma were not affected by neuraminidase treatment. The treatment has a reduced migration rate of the F band equal to that of the S band and the B band of both types closer to the origin. The genetic control of these bands is discussed.
