CircLigase II Test Reagents

  • CircLigase II kit is on back order
  • I have plenty of enzyme but low on 10X buffer, 5M Betaine, and 50mM MnCl2

Reagents

Justin made from dry reagent

  • 5M Betaine
  • 50mM MnCl2

Neither worked as well as kit-provided reagents

Ordered from 3rd party companies

  • 5M Betaine from SigmaAldrich
  • 50mM MnCl2 from Trevigen
