Nitro blue tetrazolium chloride (NBT)

Supplier: PanReac AppliChem

Description: Nitro blue tetrazolium chloride (NBT)

Nitro blue tetrazolium chloride (NBT), yellow powder

Supplier: MP Biomedicals

Description: p-Nitroblue Tetrazolium Chloride is a substrate for dehydrogenases and other oxidases and precipitating agent for fibrinogen.

Nitro blue tetrazolium chloride (NBT) for molecular biology

Supplier: 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.

Ultra-low temperature refrigerated circulators

Supplier: JULABO GmbH

Description: Ultra-low temperature refrigerated circulators for heating and cooling. The units are suitable for external temperature applications with simultaneous operation in the bath tank. The units provide particularly high heating and cooling capacities for rapid heating and cooling times even for large volume, external systems. FP models offer proportional cooling control to ensure energy saving performance and to reduce heat generation to the environment. Models with the designation W are water cooled. All models have handles and castors which allow easy transportation and drain ports for conveniently draining the bath fluid. The units offer an improved insulation to prevent ice formation and have a filling level display. Typical applications: Temperature control of jacketed reaction vessels, autoclaves, mini plant installations, kilo labs, freezing point determination, calibration at low temperatures and petroleum testing.

Cryo-Compact circulators, CF series

Supplier: JULABO GmbH

Description: Compact refrigerated/heating circulators which can be used on benchtop or in a fume hood, ideal for temperature control of distillation apparatus or mini plant installation. All four models feature pump connections for external temperature applications and a bath opening for temperature control of small objects directly in the circulator bath. The maximum ambient temperature of +40 °C and air cooled ventilation means the units can be positioned alongside other units or directly in a fume hood.
