• NEBuffer 3.1

1. Of the over 3,000 known restriction endonucleases, BstEII is one of the few that produces extensions of more than 4 bases.
2. May exhibit Star Activity in NEBuffer 2.1 and CutSmart Buffer.
3. Based on the stability of the enzyme in the reaction, incubations longer than 1 hr will not result in improved digestion, unless additional enzyme is added. Please refer to Restriction endonuclease survival in a reaction for more information regarding this topic.
4. Not sensitive to CpG, dcm, or dam methylation.
5. Star activity may result from a glycerol concentration of > 5%.

1. Do I have to set-up digests with Time-Saver™ qualified enzymes for 5-15 minutes? Can I digest longer?
2. Why is my Restriction Enzyme not cutting DNA?
3. Why do I see a DNA smear on an agarose gel after a restriction digest?
4. Why do I see additional DNA bands on my gel after a restriction digest?
5. How many nucleotides do I have to add adjacent to the RE recognition site in order to get efficient cutting?
6. Is this enzyme sensitive to dam, dcm or mammalian CpG methylation?
