Beschreibung: Carmine is a cochineal product usually furnished as an aluminum and calcium salt of carminic acid. Carminic acid is used for human-medical cell diagnosis and serves the purpose of the histological investigation of sample material of human origin. It is suitable for staining nuclei in histological sections. It is utilised in various staining methods including the procedure for detection of glycogen and mucous substances (Best′s carmine), for nuclear staining, or vital staining.

Beschreibung: 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.

Beschreibung: Xylenol orange tetrasodium salt is a fluorochrome acid dye with complexing and chelating properties that make it useful as an indicator in the spectrophotometric detection and assay of metal ions such as calcium, cadmium, bismuth, zinc, lead, and mercury. Its tetrasodium salt especially is used as an indicator in metal titrations. It changes color from yellow to red between pH 6.4 to 10.4. It has six potentially anionic substituents, one being sulfonate, and is anionic under staining conditions and during most laboratory applications.

Beschreibung: Brilliant Blue R concentrate is a methanol based stain especially designed for staining protein in polyacrylamide but will also stain agarose gels. The stain contains methanol and acetic acid so gels do not require fixing prior to staining. Brilliant Blue R Concentrate has been used for protein band detection after nondenaturing gradient gel electrophoresis, isoelectric focussing and SDS-PAGE (sodium dodecyl sulfate polyacrylamide gel electrophoresis). For detection of protein bands following electrophoresis.
