样品制备在生物学实验中看似简单，实则对实验结果影响很大。今天与大家一起分享一款在Cell、Nature、Science等著名期刊杂志中经常出现的组织细胞破碎仪——Bullet Blender Strom Pro。使用试管击打技术，转头以每分钟几千次的频率击打试管，使管内研磨珠与样品发生剧烈振动，从而彻底破碎样品。单次可处理1-24个样品；封闭式匀浆操作，避免样品交叉污染，轻松实现组织匀浆。
Bullet Blender Storm Pro具体有哪些应用？除了代替研钵进行组织匀浆，帮助提取生物大分子，它是否还能有别的功能？让我们来一探究竟！
不要小看它小小的身板，能支持的应用可不少。可从细菌、酵母、真菌、动植物组织、小型动物等样品中提取DNA、RNA、蛋白质、亚细胞结构或化学有机物质；还可对液体、半固体、固体样品进行快速匀浆；制备纳米颗粒或脂质体；从藻类植物中分离生物燃料等。
Bullet Blender可以较低的转速提取全长染色质，在处理过程中不会导致DNA发生过度剪切。相关文献：
