Recombinant E.coli Thioredoxin, His-tagged

Cat. No.: trxA-2403E
Product Overview: Recombinant E.coli TXN protein, fused to His-tag at N-terminus, was expressed inE.coliand purified by using conventional chromatography techniques, 12.9 kDa (119aa).
Description: Thioredoxin 1(Trx) is a low molecular weight redox protein. Trx contains a redox active disulfide/dithiol group within the conserved Cys-Gly-Pro-Cys active site. It is involved in the first unique step in DNA synthesis. Trx also provides control over a number of transcription factors affecting cell proliferation and death through a mechanism referred to as redox regulation.
Source: E.coli.
Form: Liquid. In 20mM Tris-HCl buffer(pH 8.0) containing 10% glycerol 1mM DTT.
Purity: > 85% by SDS – PAGE.
Concentration: 0.5mg/ml (determined by Bradford assay).
Biological activity: Specific activity is 16~18 A650/min/mg and was obtained by measuring the increase of insulin precipitation in absorbance at 650 nm resulting from the reduction of insulin.
Activity Assay: 1. Prepare a 1ml reaction cocktail into a suitable container: The final concentrations are 5mM Tris, 63mM sodium phosphate, 1mM DTT, 0.1% (w/v) insulin, 2mM EDTA. 2. Add 2ug of recombinant E.coli thioredoxin into reaction cocktail and mix immediately. 3. Incubate at 25C for 20 minutes. 4. Record the increase in A650nm for 15 minutes.
Storage: Can be stored at +4°C short term (1-2 weeks). For long term storage, aliquot and store at -20°C or -70°C. Avoid repeated freezing and thawing cycles.
