Developmental studies inDrosophila : V. Alkaline phosphatases, dehydrogenases and oxidases in organs and whole-fly homogenates during development ofD. pseudoobscura.

Alkaline phosphatases and several dehydrogenases and oxidases separated by a microdisc electrophoresis technique have been studied during larval and early pupal development ofD. pseudoobscura salivary glands, fat body, hemolymph, body wall and whole body. Tissue-specific enzymes were observed and the qualitative differences occurring during the development are discussed.
