Bone Specific Alkaline Phosphatase (0070053) and 5'Nucleotidase (0080235) may be useful in identifying disorders of bone and liver, respectively.
FDA
The presence of heat-stable isoenzymes (i.e., germ cell and placental) will be detected but their activities cannot be differentiated from the liver isoenzyme.
