Conditions for 100% Activity

  • 1X Buffer ScaI:10mM Bis-Tris Propane-HCl (pH6.5 at 37°C), 10mM MgCl2, 100mM KCl and 0.1mg/mL BSA
  • Incubate at 37°C

Storage Buffer

  • ScaI is supplied in:10mM Tris-HCl (pH7.5 at 25°C), 50mM KCl, 1mM DTT, 0.1mM EDTA, 0.5mg/mL BSA and 50% (v/v) glycerol

Ligation and Recleavage

  • After 50-fold overdigestion with ScaI, more than 80% of the DNA fragments can be ligated and more than 90% of these can be recut

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

Digestion of Agarose-embedded DNA

  • Minimum 20units of the enzyme are required for complete digestion of 1μg of agarose-embedded lambda DNA in 16hours


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.
