商品描述

ATP-independent,non-catalyticThermostableligasethatcatalyzestheintramolecularligation(i.e.circularization)ofssDNAtemplates

  • IntramolecularEpicentre Productligationofsingle-strandedDNAendscontaining5'-phosphatesand3'-hydroxylgroups
  • ATP-independent,non-catalyticenzyme
  • CircularizesssDNA>15baseslong
  • CompatIBLewithhightemperatureligationreactionsduetothermostABIlityofCircLigase™IIenzyme

Applications

  • ProductionofssDNAtemplatesforrolling-circlereplicationorrolling-circletranscriptionexperiments.
  • ProductionofssDNAtemplatesforRNApolymeraseandRNApolymeraseinhibitorassays.
