4,4′,4′′,4′′′-(Porphine-5,10,15,20-tetrayl)tetrakis(benzenesulphonic acid) tetrasodium salt hydrate

Fornitore: SIGMA-ALDRICH MICROSCOPY

Descrizione: 5,10,15,20-Tetraphenyl-21H, 23H-porphine-p,p′,p,p′′′-tetrasulfonic acid tetrasodium hydrate is a water-soluble porphyrin. It is a negatively charged compound due to the presence of the sulfonate groups. It has been used to functionalize chemically converted graphene to form conductive graphene films of varying thickness.

BAPTA tetrasodium salt ≥95% (by TLC) ion chelator, for calcium determination

Codice catalogo: (50003.)

Fornitore: Biotium

Codice articolo fornitore: 50003

Codice articolo locale: BTIU50003

Descrizione: BAPTA and its derivatives are calcium chelators that are commonly used to form calcium buffers with well-defined calcium concentrations. By injecting the chelators into cells or by incubating cells with the AM ester form of the chelators, one can control the cytosolic calcium concentration, an important means to study the roles of calcium.

Arancio xilenolo sale tetrasodico in ACS Reagent grade water, Sigma-Aldrich®

Fornitore: SIGMA-ALDRICH MICROSCOPY

Descrizione: Xylenol orange tetrasodium salt is a fluorochrome acid dye with complexing and chelating properties that make it useful as an indicator in the spectrophotometric detection and assay of metal ions such as calcium, cadmium, bismuth, zinc, lead, and mercury. Its tetrasodium salt especially is used as an indicator in metal titrations. It changes color from yellow to red between pH 6.4 to 10.4. It has six potentially anionic substituents, one being sulfonate, and is anionic under staining conditions and during most laboratory applications.
