Application Details

Application Notes: Aldose reductase 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 1 mL reaction mix into a suitable container : The final concentrations are 0.1 M sodium phosphate (pH 7.0), 11 mM DL-glyceraldehyde, 0.1 mM NADPH.
   2. Add 50 µL of recombinant AKR1B1 solution with various concentrations (2.5 µg, 5 µg, 15 µg) in 750 µL reaction buffer.
   3. Mix by inversion and Incubate at 25 °C for
   2.5 minutes.
   4. Add 200 µL of 50 mM DL-glyceraldehyde as a substrate and immediately mix by inversion.
   5. Record the increase at A340 nm for 3 minutes.

Background: Aldose reductase (AKR1B1) is a member of the aldo-keto reductase (AKR) superfamily and catalyzes the NADPH-dependent reduction of a wide variety of carbonyl-containing compounds to their corresponding alcohols. This protein is implicated in the development of diabetic complications by catalyzing the reduction of glucose to sorbitol. Recombinant Aldose reductase (AKR1B) protein was expressed in E. coli and purified by using conventional chromatography techniques.
