技术指标

Our Abpromise guarantee covers the use of ab99238 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

  • 生物活性Specific activity is > 30 units/mg, and is defined as the amount of enzyme that cleaves 1umole of oxalacetate and beta-NADH to L-malate and beta-NAD per minute at pH7.5 at 25°C

    Activity Assay

    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 and equilibrate to 1°C and monitor at A340nm until the value is constant using a spectrophotometer.
    4. Record the increase at A340nm for approximately 2 minutes

Could you tell me whether these proteins are also active in catalysing the reverse of that reaction, as in the generation of NADH and oxaloacetic acid from malate and NAD+?



The MDH2 protein is biologically active which means it...
