关于克污渍：How stains and counterstains workVirtual Lab Simulation
该简短的靶向模拟适用于全长的“革兰氏污渍：识别和区分细菌”模拟。
您是否知道世界上几乎所有500万亿亿英里的细菌都可以分为革兰氏阴性或革兰氏阳性群体？您是否曾经想过细胞壁的结构成分如何被染色？潜入微观世界，发现革兰氏阴性过程的五颜六色的魔法！
探索细菌细胞壁结构
Compare and contrast the cell wall of Gram-positive and Gram-negative bacteria by diving into their microscopic samples and observing how the cell wall structures retain certain reagents during the experiment. Discover how the four reagents of the Gram stain interact with structural components of the cell wall to color the bacteria.
Interpret given samples using a microscope
Being able to tell the difference, you will use a light microscope to interpret the results of a given Gram stain. View the microscopic image on the computer screen, and remember to apply immersion oil to increase magnification! Will you be able to identify the presence of bacteria?
Get Started Now
Have you ever wondered how the bacteria cell actually gets stained during Gram staining procedure? Dive into the world of microbiology with us! Discover how the cell retains a certain colour during the experiment and to differentiate it under the microscope!
