Abstract: | The assembly zone is a morphologically distinct region in the insect integument that lies between the epidermis and its principal secretory product, the lamellate cuticle. Despite its central location in the process of cuticle formation, little is known about its structure or function. Using various antisera we have shown that in Drosophila melanogaster larvae and pupae the assembly zone is antigenically distinct from the overlying lamellate cuticle. This observation suggests that this region does not contain lamellae in the process of assembling but rather is a stable and permeable matrix through which lamellar components travel in the process of cuticle formation. Curiously an antigen present in the assembly zone was also contained in the moulting gel, indicating a heretofore unsuspected chemical relationship between these two materials. |
