描述: 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.

描述: Phenolphthalein is an acid base indicator. It is a weak acid, which is colorless in acidic solution and turns puce pink in alkaline solution. Phenolphthalein is genotoxic. It might cause oxidative damage and binds to estrogen receptors. Phenolphthalein solution is a synthetic indicator. It is colorless in acidic and neutral conditions. Phenolphthalein gives pink color when added to a base, therefore it is considered as a base indicator.

描述: Zinc formalin fixative is a non-precipitating fixative. This fixative is compatible with histochemical, immunochemical and special stains. It may be used with automated tissue processors and also in manual methods. The zinc chloride component of the formulation increases the rigidity of cellular components to withstand subsequent processing, sectioning and staining procedures. Tissue specimens initially fixed using 10% neutral buffered formalin solution may be post-fixed using the zinc formalin fixative.
