Formalin-free fixation agent for histological stains of tissue samples

摘要

The invention relates to the development of a fixation solution which effects a clear improvement of the known histological and immunological staining techniques as well as the staining techniques used in pathology. In particular, the present invention improves the quality and staining of tissue samples or tissue sections that have not been fixed with formalin. The present invention is especially advantageous for sensitive tissue that is difficult to cut when fixed with formalin, which can not only be cut with a better quality without artefacts, but also has a higher brilliance and colour stability of the stain.
