Descripción general

Product Describtion:

A selective RNA polymerase II inhibitor；
Alpha-amanitin is the main toxin of several deadly poisonous mushrooms, exerting its toxic effects by inhibiting RNA polymerase II

α-Amanitin is the major toxic bicyclic octapeptide of the Amanita phalloides mushroom that has been used in biochemical research for decades. This toxin is synthesized as a proprotein, on ribosomes, 34 to 35 amino acids in length and then cleaved at specific proline residues by an enzyme belonging to the prolyl oligopeptidase (POP) subfamily. α-Amanitin shows remarkable binding affinity for eukaryotic RNA polymerase II, slightly binds to RNA polymerase III, and shows no activity on RNA polymerase I; it has been used to determine which types of RNA polymerase are present in a given sample. The toxin works by binding to the bridging helix of RNA polymerase II inhibiting the translocation of RNA and DNA needed to empty the site for the next round of synthesis; thereby slowing the rate of transcription by over 1000 fold. α-Amanitin is an inhibitor of Pol III.
A specific and potent inhibitor of eukaryotic RNA pol II and a mild inhibitor of RNA pol III.

Nota

Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20°C. Generally, these will be useable for up to one month. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.
