The Drosophila flight muscles are used as a model system for muscle development and physiology. This video describes the flight musculature of adults and highlights a protocol to dissect developing indirect flight muscles that are suitable for RNA sequencing from pupae.

Method 2 (RNA isolation): Method 1 + TURBO DNA-free Kit | Invitrogen | AM1907 | TRIzol isolation followed by treatment with a kit to remove DNA |
Method 3 (RNA isolation): Direct-zol RNA Miniprep Plus Kit | Zymo Research | R2070S | RNA isolation in TRIzol, but over commercial columns instead of using phase separation. Recommended DNase treatment performed with Monarch Dnase I in Monarch DNase I Reaction buffer. |
Method 4 (RNA isolation): RNeasy Plus Mini Kit | Qiagen | 74134 | We used the provided DNase treatment. IFM pellets were homogenized in RTL buffer as suggested for animal tissues. |
Method 5 (RNA isolation): ReliaPrep RNA Tissue Miniprep System | Promega | Z6110 | We applied the protocol for 'Purification of RNA from Fibrous Tissues'. |
Method 6 (RNA isolation): Monarch Total RNA Miniprep Kit | New England Biolabs | T2010G | We applied the protocol for tissues/leukocytes and lysed in 300 µL of RNA Protection Reagent. |
