Application

(+)-Sodium L-ascorbate has been used:
  • as a component of cutting solution for storing brain slices of rats
  • as a component of patch pipette internal solution for imaging Ca2+ transients evoked by action potential in rat brain slices
  • as a supplement for arterial smooth muscle cell (SMC) cultures to encourage collagen production

Biochem/physiol Actions

Ascorbic acid exhibits anti-oxidant properties. It is a primary substrate for detoxifying hydrogen peroxide. Ascorbic acid is a co-factor for the synthesis of adrenal steroids and catecholamines. L-Ascorbic acid (Vitamin C) is a water soluble molecule used in a wide variety of applications, including cell culture, as a reducing agent that helps reduce oxidative stress. L-Ascorbate can be regenerated by biological systems.
