In the fields of histology, pathology, and cell biology, fixation is the preservation of biological tissues from decay due to autolysis or putrefaction. It terminates any ongoing biochemical reactions and may also increase the treated tissues' mechanical strength or stability. Tissue fixation is a critical step in the … See more In performing their protective role, fixatives denature proteins by coagulation, by forming additive compounds, or by a combination of coagulation and additive processes. A compound that adds chemically to … See more There are generally three types of fixation processes depending on the sample that needs to be fixed. Heat fixation See more • Karnovsky fixative See more Fixation is usually the first stage in a multistep process to prepare a sample of biological material for microscopy or other analysis. Therefore, … See more 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 … See more WebAbstract. Cells of Bradyrhizobium japonicum were grown in media containing either 1.0 mM or 0.5 μM phosphorus.
