Recombinant Human AKR1C1, His-tagged

• Cat.No.: AKR1C1-2028H
• Product Overview: Recombinant Human AKR1C1 protein with his tag was expressed inE.coliand purified by using conventional chromatography techniques, 38.9 kDa (343aa).

Specification

• Species: Human
• Source: E.coli
• Tag: His
• Description: AKR1C1 is a member of the aldo/keto reductase superfamily, which consists of more than 40 known enzymes and proteins. These enzymes catalyze the conversion of aldehydes and ketones to their corresponding alcohols by utilizing NADH and/or NADPH as cofactors. The enzymes display overlapping but distinct substrate specificity. This enzyme catalyzes the reduction of progesterone to the inactive form 20-alpha-hydroxy-progesterone.
• Form: Liquid. In 20mM Tris-HCl buffer (pH 8.0) containing 1mM DTT20% glycerol.
• Purity: > 90% by SDS - PAGE.
• Concentration: 0.5 mg/ml (determined by Bradford assay).

• Biological activity: Specific activity: approximately 0.15 - 0.2 units/mg. Enzymatic activity was confirmed by measuring the amount of enzyme catalyzing the oxidation of 1 micromole NADPH per minute at 25℃. Specific activity was expressed as units/mg protein.
• Activity Assay: 1. Prepare a 1.mll reaction mix into a suitable container: the final concentrations are 0.1M sodium phosphate (pH7.0), 10mM DL-glyceraldehyde, 0.3mM NADPH. 2. Add 50ul of recombinant AKR1C1 solution with various concentrations (2.5ug, 5ug, 10ug) in 750ul reaction buffer. 3. Mix by inversion and Incubate at 25℃ for 2.5 minutes. 4. Add 200ul of 50 mM DL-glyceraldehyde as a substrate and immediately mix by inversion. 5. Record the increase in A340nm for 3 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.
• Pathways: Metabolism of xenobiotics by cytochrome P450; Steroid hormone biosynthesis
