Abstract
An immunocytochemical study was performed to localize the site of hemoglobin synthesis in larvae and embryos of the insect Chironomus thummi. Heterologous antisera specific for C. thummi hemoglobins were prepared using a highly purified hemoglobin extract. Tissue samples were prepared by glutaraldehyde fixation of whole dissected larvae or whole embryos without osmium tetroxide postfixation. Epoxy resin-embedded thin sections were labeled with a direct immunogold conjugate. Immune label was localized in rough endoplasmic reticulum of fat body cells of larvae. Immune label was also present in embryos. The technique, which did not require chemical etching of the sections, proved very useful for demonstration of this intracellular protein antigen.
