Evaluation of Long-Term Cryostorage of Brain Tissue Sections for Quantitative Histochemistry

Storage of tissue sections for long periods allows multiple samples, acquired over months or years, to be processed together, in the same reagents, for quantitative histochemical studies. Protocols for freezer storage of free-floating frozen sections using sucrose with different additives have been reported and assert that storage has no effect on histochemistry, but no quantitative support has been provided.
