ISOLATIONOFRNAFROMBACTEROIDS
3 g nodules (fresh or frozen in liquid N2) were ground to a powder in mortar and pestle with liquid N2. To the powder was added ice cold 0.5 M mannitol (or sucrose), 0.05 M Tris (pH 7.5), 0.02 M Na succinate, 5 mM Na dithionite. Pass the resuspension through one layer Miracloth and rinse the cloth with 5 ml of the same buffer solution. Spin filtrate in a sterile centrifuge tube and spin 5 min 5 min at 1500 rpm.

真核细胞总RNA的制备（Total－RNA－Isolation）1
从细胞中分离RNA的纯度于完整性对于许多分子生物学实验至关重要。如Northern印迹与杂交分析、寡聚（dT）纤维素选择分离 mRNA，cDNA合成及体外翻译等实验的成败，在很大程度上决定于RNA的质量。RNA分离的最关键因素是尽量减少RNA酶的污染。快速一步法提取总RNA组织及有核细胞在匀浆过程中
