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: Readily polymerizes in aqueous solution, forming a stable free radical that inhibits protein-nucleic acid interactions. It is a potent inhibitor of ribonuclease and topoisomerase II by preventing the binding of the nucleic acid to the enzyme. It stimulates tyrosine phosphorylation processes including the Jak2/STAT5 pathway in NB2 lymphoma cells, ErbB4 in neuroblastoma cells, and MAP kinases, Shc proteins, phosphatidylinositide 3-kinase and phospholipase Cγ in PC12 cells. Inhibits apoptosis. It prevents down-regulation of Ca²⁺ -impermeable GluR2 receptors and inhibits calpain, a Ca²⁺ -activated protease that is activated during apoptosis.

Beskrivelse: Pepsin is used for proteolytic digestion of formalin-fixed paraffin-embedded (FFPE) tissue sections prior to application of antibodies. In immunohistochemistry (IHC), most commonly used fixatives such as formalin mask tissue antigens (cellular, membrane, and nuclear) by their intrinsic crosslinking. This masking results in poor or no staining in IHC. Pepsin digestion of FFPE tissue sections improves accessibility of antibodies to tissue antigens. Ready to use pepsin reagent, antigen retriever has been used for antigen unmasking in immunohistochemistry.
