Reactive Black 5 (RB5) has been: used in an optimization study on the photocatalytic degradation of RB5 dye in synthetic greywater effluent (i.e. aqueous RB5 in distilled water), in order to understand the effects of different photoreactor parameters on the degradation kinetics. As a textile dye to investigate the anaerobic reduction in upflow stirred packed-bed reactors (USPBRs) with biological activated carbon (BAC) system. Used in the performance evaluation of dye removal forlarge molecule substance.

The combination of azure A and silver staining is used for the quantification of glycosaminoglycans in agarose gels. It is also used for the staining of chromosomes in the nucleus. Azure A is a main component of the azure B/polychromed methylene blue-eosin stains family, also referred to as the Romanowsky stain. Azure A is a basic cationic dye.

Supplier: SIGMA ALDRICH MICROSCOPY

Intended for use in the silver stain (modified GMS) procedure.

Crystal violet has been used to determine cell viability. It has been used in the staining of cells for the quantification of cellular migration.

Supplier: SIGMA ALDRICH MICROSCOPY

Nile Blue A has been used for the staining of eggs before transferring them to the hosts. It has been used for the staining of cells.

Osmium tetroxide is also referred to as osmium and is mainly used as a secondary fixative of tissues. The molecule reacts with lipid moieties and is responsible for the oxidation of unsaturated bonds of fatty acids. This reaction adds density and contrast to biological samples. In normal tissues, presence of osmium results in intense black staining which can be viewed by normal eye. In addition, it can be used as a mordant (a molecule which combines with stain or dye at later stages) in electron microscopy, thereby enhancing lead staining.
