Abstract
Source: Parker, D. J., et al. Studying Mitochondrial Structure and Function in Drosophila Ovaries. J. Vis. Exp. (2017).
This video describes the general anatomy of the Drosophila ovary and features a method of dissecting ovaries for live or fixed imaging.
Protocol
This protocol is an excerpt from Parker et al., Studying Mitochondrial Structure and Function in Drosophila Ovaries, J. Vis. Exp. (2017). 1. Preparation of Drosophila (the tools required are depicted in Figure 1A) For any of the experiments described, collect Drosophila (maintained at room temperature, or 25 °C) within 5 days of eclosion and place them in a vial filled with 5 …
