Glycoproteins in the microtubular granules of the paragonial secretory cells indrosophila melanogaster meig


Cytochemical observations of the paragonial microtubular granules during the first 2 weeks after emergence have shown the ultrastructural localization of glycoprotein in peripheral or central matrices by periodic acid-thiocarbohydrazide-silver proteinate method (PATAg). The microtubules do not appear to contain glycoprotein moiety. The functional significance of the components of paragonial secretion is discussed.
