General description

Ascorbic acid, also known as vitamin C, is a water-soluble vitamin. L-Ascorbic acid is a reducing agent.

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

Packaging

25, 100, 500 g in poly bottle
1 kg in poly bottle

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.

We demonstrated that the individual graphene oxide sheets can be readily reduced under a mild condition using L-ascorbic acid (L-AA). This simple approach should find practical applications in large scale production of water soluble graphene.
