For histological investigations of biological tissues, i.e. anatomical studies under the microscope, samples are usually fixated to prevent them from decaying. Fixation is typically done by immersing ...

The two main fixation formats used by researchers are formalin fixation followed by paraffin embedding (FFPE) or snap-frozen in liquid nitrogen (referred to as Fresh Frozen or FF). There is less of a ...

The regulation of the biological fixation of nitrogen in hydric stress conditions varies with the different species of legume plants studied. This was the conclusion of Ruben Ladrera Fernández in his ...
