EcoRI restriction site:

G | AATT C
C TTAA | A

Supplied buffer: H

Effect of DNA methylation: enzyme activity is affected by CG methylase

Reaction temperature: 37°C

  • Source: Escherichia coli RY13
  • Concentration: 8–20 units/μl [High concentration: 30–60 units/µl]
  • Substrate for unit definition: lambda DNA
  • Enzyme activity is affected by CG methylase depending on the sequence following the recognition site
  • Star activity: Unrelated sites may often be cut in the presence of a high concentration of glycerol, Mn2+, or DMSO, and at low ionic strength. Enzyme activity reduces to 70 to 80 by the addition of spermine (ca. 0.2 mM), but star activity reduces to 30–50.
  • Each lot undergoes stringent quality testing including overdigestion, genome DNA analysis, ligation-recutting and pKF3 cloning
