Norbormide-Based Probes and Their Application for Mitochondrial Imaging in Drosophila Melanogaster

Methods Mol Biol. 2021:2275:279-289. doi: 10.1007/978-1-0716-1262-0_17.

Abstract

Fluorescent live imaging on Drosophila melanogaster is a microscopy technique in rapid expansion. The growing number of probes available to detect cellular components and the relatively easy genetic manipulation of fruit fly make this model one of the most used for in vivo analysis of several physiological and/or pathological processes. Here we describe the chemical synthesis of two norbormide-derived BODIPY-conjugated fluorescent probes (NRBMC009 and NRBZLW0047). Moreover, we describe the larval dissection method, and subsequent live imaging acquisition. Both probes are able to label mitochondria in different Drosophila larval tissues, which allows for the characterization of mitochondrial morphological alterations by using a simple and quick method that avoids the fixation artefacts that often occur in immunofluorescence studies.
