Eine Methode zur Trockenfixation grossflächiger Kryostatschnitte

Summary By exposure to formaldehyde vapor after freeze-drying large cryostat sections are brought into a stable form. These sections can be used for documentation and may be compared easily with autoradiograms made of the same slices. Furthermore, a method is shown of evaluating these sections with a thin-layer scanner and a 2-flow counter, or by measuring quantitatively the radioactivity of single, excised organs or parts of tissues after automatic combustion by liquid scintillation counting.
