Cpo I (Rsr II)

DNA restriction enzymes from Takara Bio are unsurpassed in quality and purity. We’ve been producing them for over 30 years and were the first manufacturers to offer commercially available restriction enzymes in Japan. Each lot of every DNA restriction enzyme undergoes stringent quality control tests. Takara Bio DNA restriction enzymes are supplied with optimized buffers that provide maximum activity during restriction enzyme digestion. Visit our Restriction Enzyme Applications pages for information on how to digest DNA, relative activity in each Universal Buffer, star activity, buffers for double digestion, effects of DNA methylation, how to inactivate enzymes, and more.

DNA Restriction Enzyme: Cpo I (Rsr II)

  • Source: Caseobacter polymorphus
  • Concentration: 10 units/µl
  • Supplied buffer: K
  • Reaction temperature: 30°C
  • Substrate for unit definition: lambda DNA
  • Genome DNA analysis: Staphylococcus aureus genome DNA
  • Effect of DNA methylation: Enzyme activity is affected by CG methylase.
  • Notice: Do not dilute. This enzyme is unstable at low concentration. The relative activity of this enzyme is 50% at 37°C, and 120% at 25°C. Addition of BSA to a final concentration of 0.01% in reaction mixture increases the relative activity up to 120% at 30°C and up to 160% at 25 degrees C.

TaKaRa follows a stringent QC process when manufacturing their restriction enzymes. Each lot of every enzyme undergoes four quality tests including: overdigestion, Genome DNA analysis, Ligation-Recutting and pKF3 Cloning.
