Supplied with: 10X OPTIZYME AarI, ScaI, PasI Buffer
Conditions for 100% Activity:

  • 1X OPTIZYME Buffer AarI, ScaI, PasI: 10mM Bis-Tris Propane-HCl (pH 6.5 at 37°C), 10mM MgCl2 , 100mM KCl and 0.1mg/ml BSA
  • Incubate at 37°C
Enzyme Activity in OPTIZYME buffers:
  • Buffer 1: 0 - 20%
  • Buffer 2: 0 - 20%
  • Buffer 3: 0 - 20%
  • Buffer 4: 0 - 20%
  • Buffer 5: 0 - 20%
Storage Buffer:
  • 10mM Tris-HCl (pH 7.5 at 25°C), 50mM KCl, 1mM DTT, 0.1mM EDTA, 0.5mg/ml BSA and 50% (v/v) glycerol
  • Ligation and Re-cleavage:
  • More than 80% of the DNA fragments can be ligated and more than 90% of these can be re-cut after 50-fold over-digestion with ScaI.
  • Digestion of Agarose-embedded DNA:
  • A minimum of 20 units of ScaI is required for the complete digestion of 1μg of agarose-embedded lambda DNA in 16 hours.
  • Notes:
    • Conditions of low salt, high enzyme concentration, glycerol concentration >5% or pH >8.0 may result in star activity.
    • Supercoiled plasmids may require up to 20-fold more ScaI for complete digestion than linear DNA.
    Methylation Effects:
    Dam: Never overlaps - no effect
    Dcm: Never overlaps - no effect
    CpG: Never overlaps - no effect
    EcoKI: Never overlaps - no effect
    EcoBI: May overlap - blocked
