For each replicate plus one, prepare the reaction mix as described in the following table:
Reagent | Stock concentration | Volume (μL) | Final concentration |
---|---|---|---|
Tris-HCl pH 8.0 + 0.2% Triton X-100 | 0.2 M | 100 | 100 mM |
DTNB in Tris-HCl pH 8.0 | 1 mM | 20 | 100 μM |
Acetyl-CoA (10 mM) | 10 mM | 6 | 300 μM |
H2O | – | 62 | – |
Add 188 μL of the reaction mix into each well of a 96 well plate (see
Add 2 μL of mitochondrial lysate from step 13 (1 μg/μL) and mix well.
Record baseline activity at λ=412 nm within 2 min at 30°C.
Add 10 μL of 10 mM oxaloacetate (final concentration 500 μM) to each well to start the reaction.
Record absorbance at λ=412 nm for 2 min at 30°C.
Example 3
A woman diagnosed with PMDD had a history of extreme cramping (pain level 10), suicidal thoughts, and difficulty with anger and anxiety. The cramping was not relieved by Midol or Aspirin. The woman was despondent even after her symptoms of PMDD left because of guilt over her behavior during this time period. She took 200 mg oxaloacetate in a hypromellose capsule carrier, and experienced immediate relief from all symptoms. She reported that it was like a 1,000 pound weight being taken off her shoulders.
Example 4
The woman in Example 3 continued to take oxaloacetate each month for the next three months and monitored her progress. She took one pill starting about 10 days before her period, and continued taking 1 pill daily until the first sign of PMS, when she increased the dosage to 2 capsules per day until the 2nd day of her period. The symptoms of PMDD completely resolved. She reported that “I am no longer a suicidal, psychotic crazy person every month. And I know it is the supplements because this will be the 3rd month with no PMDD and that is NOT a coincidence.”
