6-Aminofluorescein has been demonstrated to be useful fluorescent labeling reagent for fullerene-based liposome nanostructures termed 'buckysomes'. 6-aminofluorescein dissolved in 0,1 N NaOH can be quantified from a maximum absorbance at 490 nm. Decarboxylated 6-aminofluorescein dissolved 6 N HCl (prepare by constant boiling at 110 °C for 24 h) can be quantified from a maximum absorbance at 454 nm. Aldehyde groups are formed by oxidateive damage to proteins, which can be detected by conjugation to decarboxylated 6-aminofluorescein. 6-Aminofluorescein has been used to determine its ability to potentiate the antiviral activity of poly r (A-U).

Intended for use in the silver stain (modified GMS) procedure.

Supplier: SIGMA ALDRICH MICROSCOPY

Formalin solution (10%, neutral buffered) is a widely used fixative for samples processed for light microscopy. It requires a relatively short period of fixation. It is suitable for the long-term storage of tissue. Once properly fixed, the tissue should be able to withstand the subsequent stages of tissue processing or staining.

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.
