BmrI

Companion Products

• Monarch® Plasmid Miniprep Kit 
• Monarch® DNA Gel Extraction Kit
• Monarch® PCR & DNA Cleanup Kit (5 μg)

1. BmrI produces DNA fragments that have a single base 3´ extension which are more difficult to ligate than blunt-ended fragments.
2. BmrI cleaves DNA specifically both in the presence and absence of Mg²⁺ ions in the reaction mixture.
3. Active in the presence of EDTA.
4. May exhibit star activity in CutSmart Buffer.
5. 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.
6. Not sensitive to CpG, dcm, or dam methylation.

1. Do BmrI generated ends ligate well?
2. Is extended digestion of BmrI recommended?
3. Why is my Restriction Enzyme not cutting DNA?
4. Why do I see a DNA smear on an agarose gel after a restriction digest?
5. Why do I see additional DNA bands on my gel after a restriction digest?
