Alkaline Phosphatase Activity in Leukocytes of Some Animal Species

Abstract

Alkaline phosphatase activity (ALPA) was observed frequently in the neutrophils of the horse, cow, sheep, goat, pig, rabbit, and monkey, whereas the neutrophils of the dog and the cat were devoid of ALPA. Alkaline phosphatase activity was also detected, to a variable extent, in the eosinophils of the horse, cow, dog, and cat, and in the basophils of the cow. No ALPA was seen in the monocytes, lymphocytes, erythrocytes, and thrombocytes of all the species examined.
