ethanol fixation

Ethanol fixation is a process used in laboratories to preserve biological samples, such as cells or tissues, by immersing them in ethanol. Ethanol works by dehydrating the samples, removing water, and denaturing proteins, which halts biological activity and prevents decay. This preservation method helps maintain the structure and appearance of the samples for microscopic examination or further analysis. Ethanol fixation is simple, quick, and effective for preparing specimens, especially for histological studies, ensuring they remain stable and suitable for detailed investigation.
