Purified recombinant Human Thioredoxin1 protein Expression System: E.coli Bioactivity: Specific activity is 7-10 A650/min/mg, obtained by measuring the increase of insulin precipitation in absorbance at 650 nm resulting from the reduction of insulin. Molecular weight on SDS-PAGE will appear higher.
Thioredoxin1 protein has been used in SDS PAGE and may be suitable for use in other assays to be determined by the end user.
实验流程
Prepare a 1 mL reaction cocktail in a suitable container. The final concentrations are 1 mM Tris, 61 mM sodium phosphate, 1 mM DTT, 0.1 % (w/v) insulin, 1 mM EDTA. 2.

Thioredoxin (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. Recombinant human thioredoxin-1 was overexpressed in E. coli and purified by using conventional chromatography techniques.
