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 ...
Formalin-based fixation and paraffin embedding (FFPE) is a common method to preserve clinical samples, and FFPE tumor samples serve as valuable study materials for clinical and translational medicine ...
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 ...
