3-(4,5-Diméthylthiazole-2-yl)-2,5-diphényltétrazolium bromure (MTT) 98%, Sigma-Aldrich®

Fournisseur: SIGMA ALDRICH MICROSCOPY

Description: Thiazolyl Blue Tetrazolium Blue (MTT) may be used in measurement of cell proliferation. MTT produces a yellowish solution that is converted to dark blue, water-insoluble MTT formazan by mitochondrial dehydrogenases of living cells. The blue crystals are solubilized with acidified isopropanol and the intensity is measured colorimetrically at 570 nm. MTT has been used as a histochemical/cytochemical reagent and for the detection of NAD. ADP-linked enzyme systems in tissue cannot be detected with MTT, due to binding of the cation by the cyanide trap used. MTT is rapidly reduced to the formazan, which chelates with nickel, copper, and cobalt; the cobalt chelate has been used in oxidative systems.

Tris(hydroxypropyl)phosphine ≥80% (par 31P-RMN), Millipore®

Numéro de catalogue: (598250-1)

Fournisseur: Merck Millipore (Calbiochem‎)

Description: A water-soluble, neutral, and odorless disulfide reducing agent that is more stable and effective than DTT. THP is comparable with TCEP as a reducing agent. Its reduction capacity against oxidised glutathione is 0,232 meq/g (TCEP has a reduction capacity of 0,182 meq/g). THP is also more resistant to air oxidation as compared to DTT.

Bleu nitré-tétrazolium chlorure (NBT) pour la biologie moléculaire

Fournisseur: MP Biomedicals

Description: p-Nitroblue Tetrazolium Chloride is an NADPH-diaphorase substrate that competitively inhibits NOS (nitric oxide synthase) (IC50 = 3-4 μM). In combination with 5-Bromo-4-chloro-3-indolyl phosphate (BCIP) and an appropriate reaction buffer, Nitroblue tetrazolium forms a substrate for the colorimetric detection of alkaline phosphatase conjugates in a variety of molecular and cell biology techniques.

p-nitro blue tetrazolium is used for the detection of alkaline phosphatase on western blots. It has also been used as a redox indicator for other enzymatic reactions including dehydrogenases, threonine deaminase, glucose-6-phosphate dehydrogenase, phosphofructokinase on polyacrylamide gels, oxidases on polyacrylamide gels, and pentose shunt dehydrogenases. Redox and halfwave potentials have been determined for p - nitro blue tetrazolium. It has also been used as a colorimetric indicator of bacterial infection in blood samples.
