A method for the permeabilization of live Drosophila melanogaster larvae to small molecules and cryoprotectants.
The larvae of Drosophila melanogaster is a model organism widely used to study the muscular and nervous systems. Drosophila larvae are surrounded by a waxy cuticle that prevents permeation by most substances. Here we develop a method to remove this layer, rendering the larvae permeable to small molecules without causing death, allowing the larvae to develop to adulthood and reproduce. Permeability was assessed using fluorescein diacetate dye uptake, and mortality upon exposure to toxic levels of ethylene glycol (EG) and Dimethyl sulfoxide (DMSO). Potential uses for this method include drug delivery, toxicity assays, cryopreservation, staining, and fixation.
期刊介绍：
Fly is the first international peer-reviewed journal to focus on Drosophila research. Fly covers a broad range of biological sub-disciplines, ranging from developmental biology and organogenesis to sensory neurobiology, circadian rhythm and learning and memory, to sex determination, evolutionary biology and speciation. We strive to become the “to go” resource for every researcher working with Drosophila by providing a forum where the specific interests of the Drosophila community can be discussed. With the advance of molecular technologies that enable researchers to manipulate genes and their functions in many other organisms, Fly is now also publishing papers that use other insect model systems used to investigate important biological questions.
Fly offers a variety of papers, including Original Research Articles, Methods and Technical Advances, Brief Communications, Reviews and Meeting Reports. In addition, Fly also features two unconventional types of contributions, Counterpoints and Extra View articles. Counterpoints are opinion pieces that critically discuss controversial papers questioning current paradigms, whether justified or not. Extra View articles, which generally are solicited by Fly editors, provide authors of important forthcoming papers published elsewhere an opportunity to expand on their original findings and discuss the broader impact of their discovery. Extra View authors are strongly encouraged to complement their published observations with additional data not included in the original paper or acquired subsequently.
