The therapeutic areas where the formalin-fixed and paraffin embedded specimens are most commonly used are:Oncology: FFPE tissues are key to the study of oncology, or the study of cancer, as preserved tumor tissues exhibit very characteristic morphologies. When dissolved in water it is called formalin, which is commonly used as an industrial disinfectant, and as a preservative in funeral homes and medical labs. Formaldehyde is quickly broken down in the air – generally within hours. phosphates may precipitate out of solution and into the tissue and cause issues with sectioning. Mechanism of Formalin Fixation. Intravesical formalin is most effective with a success rate of 70 to 80% (100% in our patients).Formalin is instilled under anesthesia.Other products can be used (silver nitrate, alum) but with less efficiency.Hyperbaric oxygen also gives good results but requires a large number of sessions (average 20).In our training, the TissuePro Technology is a biomedical technology provider in solutions used in the various biomedical fields and pharmaceutical industry.

As formalin is a strong disinfectant and tissue hardener, it''s used for preserving biological and anatomical specimens. Formaldehyde (/ f ə r ˈ m æ l d ə h aɪ d / fer-mal-duh-hahyd, also / f ɔːr ˈ m æ l d ə h aɪ d / fawr-) (systematic name methanal) is a naturally occurring organic compound with the formula CH 2 O (H−CHO). Researchers often use FFPE tissue to look for specific proteins. The formalin used for this application is a formulation that contains 10% formalin (3.7% formaldehyde) and buffers that neutralize the solution to reduce damage (artifact) to tissues during preservation.
