Gene Editing with CRISPR/Cas9 - Breakthrough in Genome Engineering

The CRISPR/Cas9 system is one of several different bacterial systems for defense against viral attacks. It consists of two main components. One is a small piece of RNA which binds to the viral target…

冷冻透射电子显微镜的投入式冷冻技术：应用

低温下观察完全含水、未染色样本的透射电子显微镜（cryo TEM）是结构生物学、细胞生物学、药理学和其他科学分支的通用工具。通过将标本放入冷冻剂中进行超快速冷冻（投入式冻结）是一种常用的方法，用于制备在透射电镜观察的各种标本。本文是对投入式冷冻的补充，介绍了在不同领域使用投入式冷冻标本的三种冷冻TEM应用。

冷冻断裂与冷冻蚀刻基础介绍

冷冻断裂是一种将冰冻样本劈裂以露出其内部结构的技术。冷冻蚀刻是指让样本表面的冰在真空中升华，以便露出原本无法观察到的断裂面细节。金属/碳复合镀膜能够实现样本在SEM（块面）或TEM（复型）中的成像，主要用于研究如细胞器、细胞膜，细胞层和乳胶。这项技术传统上用于生物学应用，但现在逐渐在物理学和材料科学中展现出重要意义。近年来，研究人员通过冷冻断裂电子显微镜，尤其是冷冻复型免疫标记（FRIL），对膜蛋…
