Lors de la coloration des disques imaginaux Drosophila, souvent une dissection rugueuse est effectuée lorsque les disques sont exposés, mais restent attachés au corps. Une fois tachés, les disques d’intérêt sont isolés et montés. Le protocole d’exemple démontre une procédure pour la dissection et le montage imaginaux de disque d’aile.
Protocol
Ce protocole est un extrait de Morimoto et Tamori, Induction and Diagnosis of Tumors in Drosophila Imaginal Disc Epithelia, J. Vis. Exp. (2017). 1. Dissection des larves Recueillir les larves errantes du troisième stade à l’aide d’un bâton en bois ou de forceps contondants, les génotyper au moyen de marqueurs fluorescents appropriés(p. ex.,EGFP) au microscope stéréoscopique à fluorescence et les placer dans un plat de dissection…
