Formalin 4 % buffered according to Lillie

Formalin 4 % buffered according to Lillie is in vitro diagnostic agent, for use in histology and scientific laboratories. The solution consists of aqua dist. / deionized water, sodium dihydrogen phosphate monohydrate, di-sodium hydrogen phosphate dihydrate Ph.Eur., BP and formaldehyde. It is used to fix biological samples, preserve their structure and keep them available for later studies.

Chemically, formaldehyde is an aldehyde (HCHO) and is included as a stabilized form. Sodium dihydrogen phosphate monohydrate and di-sodium hydrogen phosphate dihydrate act as buffer substances. In the presence of formalin, formaldehyde reacts with connective tissues and proteins of biological samples and stabilizes them.

Fixation occurs through the cross-linking of amino acids in macromolecules such as proteins and nucleic acids, which maintains the structure of the sample unchanged. This enables the subsequent analysis and interpretation of tissue samples, e.g. in cancer diagnostics or in the investigation of inflammatory processes.

The molarity of the solution is 10.075 mol/L, the osmolarity concludes from this to 20.15 mOsm/L and the buffer capacity has a pH range of 6.8 to 7.2. Thus, Formalin 4 % buffered according to Lillie is an ideal solution for the fixation of biological samples so that precise analysis is possible.

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.
