fixation methods

Fixation methods refer to techniques used to preserve biological tissues or samples so they maintain their structure for examination or analysis. These methods typically involve applying chemicals or physical conditions to stop decay, prevent decomposition, and stabilize cellular components. Common chemical fixatives, like formaldehyde, cross-link proteins and other molecules, locking them in place. Physical methods may include freezing or drying tissues. Proper fixation is essential for accurate microscopy, research, and diagnosis, ensuring tissues retain their natural architecture and details for detailed study or testing.
