WebFixing tissues with a ratio of NBF volume to tissue volume of 2:1 for 48 hours at 20-22°C was enough to assure a proper fixation and infiltration of the tested tissues and there is no objective reason to expect that other tissues will not behave similarly. In both immersion and perfusion fixation processes, chemical fixatives are used to preserve structures in a state (both chemically and structurally) as close to living tissue as possible. This requires a chemical fixative. Crosslinking fixatives act by creating covalent chemical bonds between proteins in tissue. This anchors soluble proteins to the cytoskeleton, and lends additional rigidity to the tissue. Preservat…
