General description

3-Indoleacrylic acid (IAA) is a chemical used for the induction of gene transcription. This expression system requires that the gene of interest is cloned in plasmids containing the trpE promoter.

application

Suitable for induction of gene transcription in systems controlled by the trpE promoter.

Biochem/physiol Actions

3-Indoleacrylic acid helps to block the mycelial growth of Neurospora crassa. As a result, the cells accumulate indoleglycerol phosphate, which influences the rate of tryptophan synthetase.[1]
