oocytes are widely used to study mechanisms of RNA function and biogenesis. While the large size of oocytes is amenable to both biochemical and imaging approaches, the relative opacity of the yolk-rich cytoplasm has limited high-resolution imaging of endogenous RNAs. Here, we present a protocol that combines multi-probe fluorescence in situ hybridization with cryosectioning to provide a highly sensitive means of imaging endogenous oocyte RNAs.
卵母细胞被广泛用于研究RNA功能和生物发生机制。虽然卵母细胞体积较大,适合生化和成像方法,但富含卵黄的细胞质相对不透明,限制了对内源RNA的高分辨率成像。在这里,我们提出了一种将多探针荧光原位杂交与冷冻切片相结合的方案,以提供一种高灵敏度的成像内源卵母细胞RNA的方法。
