Puah, Wee Choo, and Martin Wasser. "Live Imaging of Muscles in Drosophila Metamorphosis: Towards high-throughput gene identification and function analysis." Methods (2015).
Objects can be recovered gently for onward growth or orthogonal analysis and avoids risk of hyperthermal shock from use of LMP agarose.
