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.

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.

Disclaimer

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