Characteristics: Purified recombinant E.coli TRXB protein
Expression System: E.coli
Bioactivity: Specific activity is 4-5 units/mL, and was measured in a coupled assay with DTNB and NADPH. The amount of TNB generated by NADPH was measured in absorbance at 412 nm.

Application Details

Application Notes: TRXB protein has been used in SDS PAGE and may be suitable for use in other assays to be determined by the end user.

Assay Procedure:

1. Prepare a 0.7 mL reaction mixture into a suitable container: The final concentrations are 107 mM potassium phosphate, 17 mM EDTA, 0.7 mM beta-NADPH, 0.05 % BSA, 0.014 % (w/v) thioredoxin, 7 mM DTNB, 5 µg, E. coli TRXB.
   2. Equilibrate to 25 °C and monitor the A412 nm until the value is constant using a spectrophotometer.
   3. Add 35 µL of 107 mM DTNB into reaction mixture and mix immediately.
   4. Record the increase in A412 nm for 2 minutes.

Restrictions: For Research Use only

Target Details

Target: Thioredoxin Reductase (TrxR)

Alternative Name: TRXB

Background: TRXB(Thioredoxin reductase) is a ubiquitous enzyme which is involved in many cellular processes such as cell growth, p53 activity, and protection against oxidative stress. The mammalian Thioredoxin reductase reduces thioredoxins as well as non-disulfide substrates such as selenite, lipoic acids, lipid hydroperoxides, and hydrogen peroxide. Recombinant E. coli TRXB protein was expressed in E. coli and purified by using conventional chromatography techniques.
Alternative Names: protein, Thioredoxin reductase protein, FAD/NAD(P)-binding protein, Thioredoxin reductase JW0871 protein, TRXR., ECK0879 protein

Molecular Weight: 34.6 kDa (321 AA)
