measuring replicative life span in the budding yeast

老化是一种退化性的过程，特点是逐渐恶化的细胞成分和细胞器造成的死亡率。芽殖酵母<em&gt;酿酒酵母</em&gt;已被广泛用于研究生物学的老化，以及酵母长寿的几个因素已经证明，在多细胞真核生物中，包括蠕虫中保守，苍蝇和老鼠<sup&gt; 1</sup&gt;。由于缺乏容易量化的年龄相关的表型酵母中的老化，已经检测几乎完全通过测量细胞在不同语境中的寿命，具有两种不同的生活中常见的用法的跨度范式<sup&gt; 2</sup&gt;。按时间的寿命是指时间长度，母细胞可以生存在一个不分裂的，静止的状态，和建议，以作为在多细胞真核生物有丝分裂后细胞老化的典范。复制的寿命，相反，是指前，一位母亲细胞衰老所产生的子细胞的数目，被认为是提供了一个模式在分裂活跃的细胞老化。在这里，我们提出了一个测量的芽殖酵母中的母亲细胞中的复制寿命的广义协议。复制寿命试验的目的是确定每个母细胞芽多次。母亲和女儿的细胞可以很容易地使用一个标准的光镜下（总放大倍率160X），如蔡司Axioscope 40或其他类似的模式，由经验丰富的研究员有区别的。配备一个光纤针使用手册显微子细胞从母细胞的物理分离。典型的实验室酵母菌株的产生20-30％的母亲的女儿细胞和寿命实验需要2-3周。
