Tetrazolium blue chloride (BTC) is a colorless tetrazolium compound that upon reduction forms a colored diformazan. The reactivity has been applied to the analysis of reducing compounds including the nanomolar detection of reducing sugars and carbidopa and methyldopa. BTC has been used for histological staining of mouse coronal brain sections and rat brain sections. In combination with 4-nitrocatechol, tetrazolium blue chloride forms a ternary complex with molybdenum(VI) for extraction and spectrophotometric determination of molybdenum. It has also been used to stain Francisella tularensis cells for tularemic microagglutination test.

Formalin solution, neutral buffered, 10% is the most commonly used fixative for light microscopy. It requires a relatively short period of fixation. It is suitable for the long-term storage of tissue. Once properly fixed, the tissue should be able to withstand the subsequent stages of tissue processing or staining. 10% NBF is well suited for large throughput laboratories, and requires a relatively short period of fixation, but can also be used for the long-term storage of tissue. Formalin fixation is thought to form between the aldehydes and the proteins, creating a gel, thus retaining cellular constituents in their in vivo relationship.
