Abstract
  1. The disruption of various types of tissue-culture cells by (a) incubation in solutions of 1.2 M-glycerol and (b) transfer of the glycerol-loaded cells to relatively hypo-osmotic solutions of 0.25 M-sucrose was studied. 2. Bivalent cations (2mM-Mg2+) were generally included to preserve the nuclei, but some cells (polyoma-virus-transformed baby-hamster kidney cells) failed to be disrupted adequately under these conditions. 3. Other cells (mouse-embryo fibroblasts) required additional gentle Dounce homogenization to effect complete cell breakage. 4. Purification of the whole homogenate was carried out by a combination of differential centrifugation and sedimentation or flotation through sucrose gradients. 5. Enzyme analysis showed that plasma-membrane, endoplasmic-reticulum and mitochondrial fractions were obtained in good yield and purity.
摘要
  1. 研究了通过以下方式对各种类型的组织培养细胞进行裂解:(a) 在1.2 M甘油溶液中孵育,以及(b) 将加载了甘油的细胞转移至0.25 M蔗糖的相对低渗溶液中。2. 通常会加入二价阳离子(2 mM Mg2+)以保存细胞核,但某些细胞(多瘤病毒转化的幼仓鼠肾细胞)在这些条件下未能被充分裂解。3. 其他细胞(小鼠胚胎成纤维细胞)需要额外进行轻柔的杜恩斯匀浆以实现完全的细胞破碎。4. 通过差速离心以及通过蔗糖梯度进行沉降或浮选相结合的方法对整个匀浆进行纯化。5. 酶分析表明,获得了高产率和高纯度的质膜、内质网和线粒体组分。
