title: Tissue alkaline phosphatase activity in selected freshwater teleosts.
abstract: 1. Kinetic studies of tissue alkaline phosphatase activity were carried out on eight species of teleost fishes taken from the Mississippi River. 2. Liver alkaline phosphatase activity expressed in mumoles of p-nitrophenol released per minute per gram of protein were as follows: Micropterus salmoides, 20.31; Stizostedion vitreum, 19.22; Pomoxis nigromaculatus, 18.76; Lepisosteus platostomus, 16.26; Esox lucius, 16.14; Hiodon tergisus, 13.83; Ictalurus punctatus, 10.87; Aplodinotus grunniens, 7.94. 3. Specific activity of the kidney alkaline phosphatase was about ten times the level of liver alkaline phosphatase for the species examined.
