Formaline 7,5 %, buffered pH 7.0
The solution is used as an in vitro diagnostic agent, particularly in histology, where it is used to fix tissue samples prior to further processing and analysis. Fixation stabilizes and preserves tissue structures, allowing detailed examination under the microscope.
The solution forms methylene bridges that cross-link proteins and nucleic acids, enabling effective fixation of cell structures. This product is suitable as a routine fixative in histology as well as scientific laboratory applications, providing consistent, reliable results. At the same time, the morphology of the tissues is preserved and their structural details are clearly visible.
The molarity of the formalin solution is approximately 2.5 mol/L, and that of the phosphate buffers is approximately 0.1 mol/L. The buffer capacity, which indicates how well the buffer can resist changes in pH, is about 0.15 mol/L.

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.
