Alizarin red S (sodium salt), Sigma-Aldrich®

Supplier: SIGMA ALDRICH MICROSCOPY

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.

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.
