Formaldehyde fixation improves fluorescence patterns of tissues within maize (Zea mays) leaf cross sections. Treatment with a paraformaldehyde fixative solution revealed distinctive blue/green ...

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 ...

For decades, formalin-fixing paraffin-embedding has been the preferred method for preserving biological samples for diagnostic research. Formalin is relatively inexpensive and can be used to preserve ...
