Several fixatives are used in histology, each with specific properties suitable for different tissue types and purposes. Common fixatives include:
Formaldehyde: Widely used due to its ability to preserve a broad range of tissues. Glutaraldehyde: Effective for electron microscopy due to its ability to cross-link proteins rapidly. Alcohol (Ethanol or Methanol): Used for cytological smears and quick fixation. Bouin's Solution: Excellent for soft and delicate tissues, enhancing color contrast.
