5,5'-Dithiobis(kyselina 2-nitrobenzoová), Molecular Biology Grade

Katalógové číslo: (BC87)

Dodávateľ: G BIOSCIENCES

Opis: Ellman's reagent is a versatile, water-soluble compound for quantifying free sulfhydryl groups in solution. It reacts with a free sulfhydryl group to yield a mixed disulfide and 2-nitro-5-thiobenzoic acid (NTB), a measurable yellow colored product at 412nm.
Ellman's reagent is very useful as a free sulfhydryl assay reagent due to its high specificity for -SH groups at neutral pH, high molar extinction coefficient and short reaction time.

Nitro modř tetrazolium for molecular biology

Dodávateľ: MP BIOMEDICALS

Opis: 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.
