cellular fixation

Cellular fixation is a laboratory process used to preserve cells or tissue samples in a life-like state by stabilizing their structure and preventing decay or changes over time. This is achieved by applying chemicals, known as fixatives, that crosslink proteins and other cellular components. Fixation allows scientists to examine cells under a microscope with minimal alteration, helping in accurate study of their structure, composition, or identifying specific molecules. It’s essential for many diagnostic tests and research, ensuring the sample remains intact and representative of its original state for analysis.
