所谓TEM，就是一个放大镜叠加了一台照相机。这台放大镜的放大倍数比较高，可高达一百万倍。当然，抛开分辨率谈放大倍数都是耍流氓，那么，TEM的分辨率有多高呢？答案是 it depends。一般来说，TEM的分辨率要在1到2个纳米，STEM更高，但是STEM得成像技术类似于SEM，但用的不是二次电子。我

一、偏光显微镜的特点偏光显微是鉴定物质细微结构光学性质的一种显微镜。凡具有双折射性的物质，在偏光显微镜下就能分辨的清楚，当然这些物质也可用染色法来进行观察，但有些则不可能，而必须利用偏光显微镜。偏光显微镜的特点，就是将普通光改变为偏振光进行镜检的方法，以鉴别某一物质是单折射性（各向同性）或双折射性（

关于多聚赖氨酸的配制、保存、使用总结与问题1
因为自己做PC12细胞培养，想在接种前将培育皿用多聚赖氨酸包被，到论坛里搜索了下，关于多聚赖氨酸的帖子不少，看了一些帖子，将大部分收集在此。个人觉得关于多聚赖氨酸的配置、保存、使用各方面问题，这些帖子里面都解释了。注：我只是摘了一个帖子里某段或某句话。一般一段话来自某一位朋友。一、常用的多聚赖氨酸包
