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 μl 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.
