PreparationofMitochondriafromRatLiver
Preparation of Mitochondria from Rat LiverRat liver is an ideal source for functional intact mitochondria for a number of reasons. We use Sprague-Dawley albino male rats for our studies. Female rats can be used, however for serious studies we usually stick to males to avoid complications due to the estrous cycle. Animal tissue is preferable to plant tissue because they do not have cell walls, which make homogenizatio......阅读全文

细胞组织消化常用的几种酶的选择
直接从生物体获取的组织，一般需要将其消化成单个细胞才能进行体外培养。这种直接从离体组织获得的细胞，更接近于生物体内的生活状态，且生物性状尚未发生很大改变，因此在药物筛选、细胞移植、类器官培养、肿瘤研究等众多领域备受欢迎。但组织消化过程中常遇到多种问题，例如消化不完全、细胞死亡率高等。如何克服这些问题
