Tissue samples may be snap frozen using PolyFreeze with isopentane and liquid nitrogen, dry ice (slush/slurry or bunker), or in a cryostat. PolyFreeze media do not cause autofluorescence and can easily be washed away during tissue fixation when rinsed prior to staining. Once rinsed off the slide, there is no trace of the support matrix to interfere with staining or immunohistochemistry (IHC) reactions.

In Schaeffer-Fulton`s method, a primary stain-malachite green is forced into the spore by steaming the bacterial emulsion. Malachite green (Schaeffer & Fulton`s Spore Stain A: Cat. No. 90903) is water soluble and has a low affinity for cellular material, so vegetative cells may be decolorized with water. Vegetative cells are then counterstained with safarin. The components and the method are also available as kit (Cat. No. 04551).

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.

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.
