General description

Recombinant, yeast thioredoxin reductase expressed in E. coli. Yeast thioredoxin reductase is a flavoprotein that has no selenocysteine (SeCys). It catalyzes the NADPH-dependent reduction of thioredoxin as well as other endogenous and exogenous proteins. Plays an important role in many aspects of cell function, including protection against oxidative stress/injury, cell growth and transformation, and the recycling of ascorbate from its oxidized form.

Warning

Toxicity: Standard Handling (A)

Unit Definition

One unit is defined as the amount of enzyme that will cause an absorbance change of 1 at 412 nm using 200 µM NADPH and 5 mM DTNB, per min at 25°C, pH 7.0.

Physical form

Lyophilized from 150 mM NaCl, 20 mM phosphate buffer, pH 7.4.

Reconstitution

Following reconstitution, aliquot and freeze (-70°C). Stock solutions are stable for 1 month at 4°C or 3 months at -70°C.
