What Are the Common Methods of Tissue Preservation?
There are several methods used in tissue preservation, each with its own advantages and limitations:
Fixation: The most common method involves using fixatives like formaldehyde or glutaraldehyde to cross-link proteins and halt biological processes. Cryopreservation: This method involves freezing tissues, often using liquid nitrogen, to preserve cellular and molecular structures. Embedding: Tissues are embedded in media like paraffin wax or resin for sectioning and microscopic examination.
