Ethidium homodimer is a red fluorescent dye. It cannot cross an intact plasma membrane, but can easily pass through a damaged plasma membrane. Ethidium homodimer is used to check membrane integrity. One molecule of EthD-1 will non-selectively bind four base pairs in dsDNA.

Bromocresol green is a sulfonephthalein dye. It is mainly used for measuring serum albumin. In acidic conditions, bromocresol green interacts with albumin, thereby resulting in an increase in absorbance at 630 nm. The change in absorbance is linked with the concentration of albumin. Bromocresol Green is also a pH indicator, changing from yellow (pH 3.8) to blue color (5.4). It is widely used as a colloidal pigment.

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.

A dual-emission potential-sensitive probe that can be used to measure mitochondrial membrane potential. JC-1 is a green-fluorescent (λex 520 nm) monomer at low membrane potential. At higher potentials, JC-1 forms red-fluorescent (λem 596 nm ) "J-aggregates," which exhibit broad excitation and very narrow emission spectra. The ratio of red to green fluorescence of JC-1 is dependent only on membrane potential, and not influenced by mitochondrial size, shape, or density.
