Study Notes
Antibody reaction & Microscopy
- The labelled antibody reaction is allowed to proceed with tissue sections.
- After the antigen-antibody reaction occurs, the excess antibody is washed away.
- Electrons passed through the specimen are focused by magnetic lenses, and then the image is displayed on a fluorescent screen similar to a TV screen.
- The image is then photographed.
- Most cells are visible only under a microscope
- Cells need a large surface area of plasma membrane to adequately exchange materials.
- Cell shape varies between different parts of the organism.
- Microscopes are instruments used for viewing objects too small to be seen with the naked eye.
- Microscopes are essential tools of cell biologists.
