Asc gutest 1

Application in HRR

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:
  1. Weigh 1.584 g of ascorbate sodium salt and dissolve in 10 mL H2O
  2. To prevent autoxidation, adjust pH to approx. 6 with ascorbic acid (a 137.6 mg.mL-1 solution of pH 2).
  3. Divide into 0.2 mL portions.
  4. Store frozen at -20 °C.
Preparation of 1000 mM stock solution (dissolved in H2O) for use in 0.5-mL O2k-chamber:
  1. Weigh 1.980 g of ascorbate sodium salt and dissolve in 10 mL H2O
  2. To prevent autoxidation, adjust pH to approx. 6 with ascorbic acid (a 137.6 mg.mL-1 solution of pH 2).
  3. Divide into 0.2 mL portions.
  4. Store frozen at -20 °C.
