Formalin 4 % with eosin
Formalin 4% with Eosin is an aqueous solution of stabilized 37% formaldehyde and some Eosin G for color labeling of the solution. This solution is mainly used in histology and cytology for the fixation of tissue and cell samples.
Fixation is based on the chemical reaction of formaldehyde, an aldehyde, with amino groups in proteins and nucleic acids of cells. This creates methylene bridges between the biomolecules, forming a three-dimensional network. This protects the sample from further chemical changes and preserves its structure. Eosin G is included in this solution only as a color marker for the formalin and has no influence on the fixation process. At the concentration used, Eosin G is not capable of staining tissue components.
The special suitability of Formalin 4% with Eosin lies in the combination of effective fixation and easy handling. The solution is particularly suitable for the fixation of tissue sections and cell preparations before they are subjected to further processing steps such as staining, embedding or microscopy.

Instructions / Protocol / Recommendations
Verwendung:
Bei der Fixierung werden alle in der Zelle ablaufenden Prozesse unterbrochen, unter möglichst optimaler Erhaltung des Zustandes und der Struktur des Gewebes. Biochemische Prozesse wie Autolyse, Verwesung und Fäulnis werden wirkungsvoll verhindert. Fixierlösung nach Stieve eignet sich zur Fixierung von Hodengewebe und Eierstockgewebe. Die Fixierlösung ist ausschließlich für die professionelle Anwendung als in-vitro Diagnostikum im histologischen Labor vorgesehen.
