Carnoyliuoksia

Carnoyliuoksia refers to a type of fixative solution used in histology and cytology. These solutions are employed to preserve biological tissues and cells in a life-like state for microscopic examination. The primary components of a Carnoyliuoksia typically include absolute ethanol, chloroform, and glacial acetic acid. The specific proportions of these ingredients can vary, leading to slightly different formulations, but the general principle remains the same.

The ethanol in the mixture acts as a dehydrating agent, removing water from the tissue. Chloroform is a powerful solvent that aids in penetration and fixation, and it also helps to dissolve lipids. Glacial acetic acid is added to enhance nuclear staining, as it helps to swell and preserve the chromatin. Carnoyliuoksia is known for its rapid fixation properties, which can minimize cellular distortion and artifact formation compared to slower-acting fixatives.

This fixative is particularly useful for preserving glycogen and nucleic acids, as the high alcohol content prevents their leaching out. However, its strong solvent action can also lead to the dissolution of lipids, making it less suitable for studies requiring the preservation of lipid structures. Tissues fixed in Carnoyliuoksia are typically processed quickly for embedding and sectioning. The rapid penetration and fixation make it a valuable tool for researchers and diagnosticians needing to preserve delicate cellular details for subsequent analysis.
