Beskrivelse: Ponceau S is the sodium salt of a diazo dye. It is used to make a stain for rapid reversible staining of protein bands on nitrocellulose or PVDF membranes (Western blots) and also for staining protein on cellulose acetate membranes. The stain is reversed with water washes and aids in subsequent immunological detection. The following are two common stain formulations: 0.1% Ponceau S (w/v) in 5% acetic acid 2% Ponceau S (w/v) in 30% TCA, 30% sulfosalicylic acid.

Beskrivelse: Clobetasone butyrate is a corticosteroid. It can be used as a diagnostic assay manufacturing, hematology, histology. Clobetasone butyrate has been used as an internal standard for the quantitative assay of clobetasol propionate. Clobetasone butyrate has been used to analyse its bio-concentration factor (BCF) in cyprinus carpio. Clobetasone butyrate is a potent topical corticosteroid and is primarily used to treat atopic dermatitis (AD). Low dosage of this drug is used to treat dry eye in sjogrens syndrome.

Beskrivelse: 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.
