Formalin 4 %, phosphate buffer pH 7.4

Formalin 4 %, phosphate buffer pH 7.4, consists of an aqueous solution with formaldehyde, di-sodium hydrogen phosphate dihydrate and sodium di-hydrogen phosphate dihydrate. Applications are mainly in histology and pathology, where it serves as a fixative for tissue specimens. In doing so, the solution preserves cellular structure and morphology through protein denaturation and cross-linking, stabilizing tissue structure.

The chemical mode of operation is based on the reaction of formaldehyde with amino groups in proteins, resulting in covalent cross-links. These crosslinks stabilize the spatial structure of proteins and cell structures, preserving tissue samples for further analysis.

Formalin 4%, phosphate buffer pH 7.4, shows particular suitability in combination with the phosphate buffer. This buffer provides a more stable microenvironment during fixation and prevents pH fluctuations that can lead to artifacts or morphological changes. The solution provides optimal buffer capacity and stability for histological and immunohistochemical studies.

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.
