FixationofCellsCulturedinTranswellDishes
Fixation of Cells Cultured in Transwell DishesTranswell culture dishes are commonly used to culture cells so that the top and bottom of the cells can be exposed to different culture media conditions. They are commonly used with polarized epithelial cells and endothelial cells. The cells are cultured on membrane supports and processing for transmission electron microscopy is greatly facilitated if the membranes are le......阅读全文

Transwell侵袭实验
第一节 概念这里想明确两个概念，一个是Transwell，另一个是肿瘤细胞侵袭模型。1. Transwell关于Transwell这个词该如何解释，查了很多资料也未见准确的注解，我觉得可以这么理解吧，trans-这个词根有转移、转运、穿过等意思，well有小室的意思，可以从字面上理解，这是一类有通透
固氮作用（nitrogen－fixation）
分子态氮被还原成氨和其他含氮化合物的过程。自然界氮（N2 ）的固定有两种方式：一种是非生物固氮，即通过闪电、高温放电等固氮，这样形成的氮化物很少；二是生物固氮，即分子态氮在生物体内还原为氨的过程。大气中90％以上的分子态氮都是通过固氮微生物的作用被还原为氨的。生物固氮是固氮微生物的一种特殊的生理功

Transwell小室的应用
（1）共培养体系：小于3.0um孔径条件下，细胞不会迁徙通过，因此，若研究不涉及细胞运动能力，不需要细胞穿过聚碳酸酯膜，则应选择3.0µm以下孔径。常用0.4、3.0µm。常用的是0.4µm。将细胞A种于上室，细胞B种于下室，可以研究细胞B分泌或代谢产生的物质对细胞A的影响。（2）趋化性实验：可用5
