Study Notes
Slide Preparation
- Main steps: Fixation, dehydration, clearing, embedding, sectioning, mounting, and staining
Staining
- Predicting characteristics: Stain color and intensity can indicate tissue type, presence of specific molecules, and cell morphology
- Hematoxylin and Eosin (H&E): A common staining technique that helps visualize different tissue components
- Hematoxylin: Stains acidic components, such as nuclei and DNA, blue
- Eosin: Stains basic components, such as cytoplasm and extracellular matrix, pink
Section Types
- Identifying section type: The orientation of the tissue can indicate the type of section
- Cross-section: Cut perpendicular to the long axis of the structure
- Longitudinal section: Cut parallel to the long axis of the structure
- Oblique section: Cut at an angle to the long axis of the structure
- Serial section: A series of consecutive sections
Microscopy
- Resolution and detection method: Choosing the appropriate microscopy technique depends on the desired level of detail and the features to be visualized
- Light microscopy: Used for general tissue observation and visualizing cell morphology
- Electron microscopy: Used for ultrastructural details, provides higher resolution images of cellular components
Histochemical Methods
- Purpose: Used to detect and localize specific molecules, including proteins, enzymes, and carbohydrates within tissues
- Immunohistochemistry: Uses antibodies to detect specific proteins
- Enzyme histochemistry: Detects the presence and activity of enzymes
- Histochemical staining: Uses specific dyes to highlight particular cellular components or structures
