  • Product description: Abscisic acid (ABA) is a natural and active isomer of the abscission accelerating plant hormone. It has been involved in several physiological mechanisms including seed dormancy, leaf abscission, stom

Product Name:

Abscisic Acid, ABA

CAS No.:


Physical and Chemical Properties:

Appearance: White to offwhite powder
Molecule Formula: C15H20O4
Molecular weight: 264.32
Melting point: 160-161°C
Solubility: Soluble in ethanol (~20 mg/ml), chloroform, DMF (~20 mg/ml), PBS (pH 7.2) (~0.3 mg/ml), and DMSO (~20 mg/ml).


1. Stimulates the closure of stomata (water stress brings about an increase in ABA synthesis).
2. Inhibits shoot growth but will not have as much affect on roots or may even promote growth of roots.
3. Induces seeds to synthesize storage proteins.
4. Inhibits the affect of gibberellins on stimulating de novo synthesis of a-amylase.
5. Has some effect on induction and maintanance of dormancy.
6. Induces gene transcription especially for proteinase inhibitors in response to wounding which may explain an apparent role in pathogen defense.
