title: Characterization of different membrane forms of placental alkaline phosphatases.
abstract: We have extracted and purified four alkaline phosphatase forms from human term placenta. The enzymes are dependent on Mg2+ for their activity. They can be distinguished by different responses to Zn2+, vanadate and inositol derivatives.
