Asc gutest 1
- As: Ascorbate sodium salt (Sodium L-ascorbate); Sigma A 7631, 100 g, store at RT; FW = 198.1.
- Caution: Light sensitive (store solution in a dark glass vial).
'
- Preparation of 800 mM stock solution (dissolved in H2O) for use in 2-mL O2k-chamber:
- Weigh 1.584 g of ascorbate sodium salt and dissolve in 10 mL H2O
- To prevent autoxidation, adjust pH to approx. 6 with ascorbic acid (a 137.6 mg.mL-1 solution of pH 2).
- Divide into 0.2 mL portions.
- Store frozen at -20 °C.
- Preparation of 1000 mM stock solution (dissolved in H2O) for use in 0.5-mL O2k-chamber:
- Weigh 1.980 g of ascorbate sodium salt and dissolve in 10 mL H2O
- To prevent autoxidation, adjust pH to approx. 6 with ascorbic acid (a 137.6 mg.mL-1 solution of pH 2).
- Divide into 0.2 mL portions.
- Store frozen at -20 °C.
- »O2k manual titrations: MiPNet09.12
- Titration volume (2-mL O2k-chamber): 5 µL of 800mM stock solution using a 25 µL Hamilton syringe.
- Titration volume (0.5-mL O2k-chamber): 1 µL of 1000mM stock solution using a 10 µL Hamilton syringe
- Final concentration: 2 mM.
