Assay Information
1. Prepare assay buffer into a suitable container and pre-chill on ice before use: The final concentrations are 100 mM Potassium phosphate, 0.13mM beta-nicotinamide adenine dinucleotide, reduced form, 0.25mM oxalacetic acid. 2. Add recombinant MDH protein with various concentrations (0.1ug, 0.5ug, 1ug) in assay buffer. 3. Mix by inversion, equilibrate to 1 DEg C, and monitor at A340nm until the value is constant using a spectrophotometer. 4. Record the increase at A340nm for approximately 2 minutes.
