Application

EcoRI is a restriction endonuclease that is used in molecular biology applications to cleave DNA at the recognition site 5′-G/AATTC-3′, generating fragments with 5′-cohesive termini.

Biochem/physiol Actions

Recognition sequence: 5′-G/AATTC-3′
Cutting results: a 2-10-fold EcoR I overdigestion of 1 μg λ DNA substrate results in 100% cutting
Heat inactivation: 65 °C for 20 minutes.

Physical form

Solution in 10 mM Tris-HCl, pH 7.2 , 1 mM EDTA, 200 mM NaCl , 0.5 mM dithioerythritol, 50% glycerol (v/v), 0.2% Triton X- 100 (v/v), 4°C

Other Notes

Comment: Avoid suboptimal reaction conditions such as low salt, high pH (>8.0) and high glycerol (>5%) as they will alter EcoRI specificity and precipitate star activity.
One unit is the enzyme activity that completely cleaves 1 mg of λDNA in 1 hour at 37 °C in a total volume of 50 ml of 1x digestion buffer SH for restriction enzymes. 1 mg pBR322 DNA is digested completely by 2 units of EcoR I.
Supplied with 10x Restriction Enzyme Buffer SH (B3657).
