斑马鱼是用于模拟骨骼肌的人类疾病的一个新兴的系统。我们描述了一个快速,高效的方法从胚胎和幼虫的斑马鱼隔离骨骼肌肌纤维。这种方法产生了高密度的肌纤维制备适合的单骨骼肌纤维形态的研究中,蛋白质的亚细胞定位,以及肌肉生理学。

该程序的总体目标是有效地从胚胎和幼体斑马鱼中分离骨骼肌纤维。这是通过首先准备聚 L 赖氨酸涂层的盖玻片来完成的,然后在受精后 1 到 4 天,斑马鱼胚胎解离。然后从解离的胚胎中分离的肌纤维接种在聚赖氨酸盖玻片上。

最后,固定、染色和成像肌纤维以分析肌肉蛋白质。最终,可以获得通过免疫荧光显微镜检查显示肌肉蛋白质亚细胞定位的结果。与全胚胎分析等现有方法相比,该技术的主要优点是它允许更详细地研究单肌纤维形态和生理学。
