Abstract

Processes for testing immobilized biological material with generally biochemical and histochemical methods, particularly enzyme, immuno and hormone chemical methods can be improved by adhering the biological material to the surface of a support and then fixing the support to a plate. The plate is constructed in such a way that the biological material is protected from damage. Using a biological testing technique such as thin section immunofluorescence testing the invention makes it possible to carry out biochemical tests in a more rational and trouble-free manner than with hitherto known methods. If necessary, a random number of tests can be performed side-by-side on a single plate. The invention makes it possible to simply and rapidly prepare frozen section products and store them in a space-saving manner at very low temperatures. The adhesion of the frozen sections to the support can be improved by coupling chemicals which react with the tissue by bonding thereto to the support.
