title: Inter-specific analysis of Drosophila alcohol dehydrogenase by an immunoenzymatic assay using monoclonal antibodies.
abstract: Three Drosophila alcohol dehydrogenase monoclonal antibodies have been prepared and characterized. These antibodies cross-react with alcohol dehydrogenase from different species as revealed by immunoblotting assay. An enzyme-linked immunosorbent assay has been devised to quantify alcohol dehydrogenase in several species, different strains and individual larval organs. The assay detects alcohol dehydrogenase via a double-antibody sandwich assay technique giving strictly proportional values for antigen concentration and optical densities in the range of 3-30 ng of antigen per 100 microliters of sample. When alcohol dehydrogenase specific activity is compared in different larval organs a remarkable similarity is observed, whereas protein distribution varies substantially. Larval fat body and larval alimentary canal contribute 63% and 26% respectively to recovered alcohol dehydrogenase.
