Application

α-Amanitin has been used:
  • for inducing transcriptional arrest in NT2 cells prior to immunofluorescence assay
  • to induce nephrotoxicity in mice renal tissues
  • to induce and analyse genotoxicity in mice bone marrow cells by cell viability assay, comet assay and chromosomal aberration assay

Biochem/physiol Actions

Inhibits eukaryotic RNA polymerase II and III; does not inhibit RNA polymerase I or bacterial RNA polymerase; inhibits mammalian protein synthesis.
The major toxic constituent of the mushroom, Amanita phalloides, inhibits eukaryotic RNA polymerase II and III, but does not inhibit RNA polymerase I or bacterial RNA polymerase. Inhibits mammalian protein synthesis.

Disclaimer

When stored frozen in the dark, retained samples were found to be greater than 99% by HPLC after two years.

Preparation Note

Store a 1 mg/ml aqueous stock solution frozen at -20°C. It does not degrade with repeated freeze-thaw cycles. Dilute into the appropriate buffer immediately prior to use. Product is destroyed by concentrated acid or base.
