了解大分子在细胞中是否占有固定的位置常常是必要的。该方案使得有可能了解酿酒酵母中的单个核仁蛋白是留在原位还是离开并返回核仁。该方案使用早期合子,其中亲本核仁分离至少一小时。该协议表明,许多核仁蛋白质的定位实际上是高度动态的。不需要光漂白。有关本方案使用和执行的完整详细信息,请参阅。蛋白质在酵母细胞核内的移动性可以通过构建合子来判断该测定需要除灵敏的荧光显微镜之外的最小设备该方案可以在一天内完成,一旦合适的细胞可用,通常需要了解大分子是否占据细胞中的固定位置。该方案使得有可能了解酿酒酵母中的单个核仁蛋白是留在原位还是离开并返回核仁。该方案使用早期合子,其中亲本核仁分离至少一小时。该协议表明,许多核仁蛋白质的定位实际上是高度动态的。不需要光漂白。
It is often necessary to learn whether macromolecules occupy a fixed place in cells. This protocol makes it possible to learn whether individual nucleolar proteins in S. cerevisiae remain in place or depart from and return to the nucleolus. The protocol uses early zygotes in which parental nucleoli are separate for at least one hour. The protocol demonstrates that the localization of many nucleolar proteins is in fact highly dynamic. Photobleaching is not required. For complete details on the use and execution of this protocol, please refer to. The mobility of proteins within the yeast nucleus can be judged by constructing zygotes The assay requires minimal equipment other than a sensitive fluorescent microscope The protocol can be completed within one day once appropriate cells are available It is often necessary to learn whether macromolecules occupy a fixed place in cells.
