10% Neutral buffered formalin (NBF) is the most commonly used fixative for light microscopy. 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.

Fluorinert™ belongs to the group of aliphatic compounds. It is considered as a pressure-transmitting medium because it is highly inert. Fluorinert™ Electronic Liquid FC-770 is a thermally stable, fully-fluorinated liquid that has ideal properties for use as a heat transfer fluid in a variety of industries. The inertness of Fluorinert™ FC-770 permits its use as a direct contact single and two-phase coolant in certain supercomputers and sensitive military electronics. Its high dielectric strength and electrical resistivity are ideal for applications in high voltage transformers and power electronics. In the semiconductor manufacturing industry, its wide liquid range makes Fluorinert™ liquid FC-770 suited for cooling ion implanters, dry etchers and CVD machines. Its low pour point also permits its use in thermal shock and test equipment.

N,N-Dimethyl-p-phenylenediamine dihydrochloride (DMPD) has been used in the HID-AB (high iron diamine-alcian blue) staining of intestinal tract samples. N,N-Dimethyl-p-phenylenediamine dihydrochloride (DMPD) is used for the determination of peroxidase. DMPD is converted into a red pigment of semiquinone nature. It is also used in the HID-AB (high iron diamine-alcian blue) staining procedures, which are used to differentiate between sialomucin and sulfomucin in the gastrointestinal tract.

Poly-L-lysine is a positively charged amino acid polymer with approximately one HBr per lysine residue. The hydrobromide allows the poly-L-lysine to be in a crystalline form soluble in water. A small amount of product may be found in the beta structure because the HBr interferes with hydrogen bonding between amino and either the carboxyl groups or N or O containing moieties.
