CRISPR / Cas systemen bemiddelen adaptieve immuniteit in Bacteria en Archaea. Veel Cas eiwitten worden voorgesteld om op te treden als endoribonucleases handelen crRNA voorlopers van verschillende lengte. Hier illustreren we drie verschillende benaderingen voor uw crRNA substraten voor de biochemische analyse van Cas endonuclease activiteit te genereren.
