Application

3-Indoleacetic acid has been used:
  • as standard to quantify hormones
  • to modify MS (Murashige and Skoog) media for the initiation of callus
  • as an external standard in the analyses of free endogenous growth regulators

Indole-3-acetic acid (IAA) is a natural phytohormone (plant auxin) used as a supplement in media such as Murashige and Skoog media and Gamborg′s B5 media. IAA is a plant signaling molecule involved in plant organogenesis and growth control.
