T7 Endonuclease I
T7 Endonuclease I
| CAT.NO | UNIT |
|---|---|
| E028 | 1000 U (100 μl) |
| Description | T7 Endonuclease I recognizes and cleaves mismatched DNA, heteroduplex DNA, cruciform DNA, Holliday structures and/or junctions, as well as nicked double-stranded DNA. This enzyme has a preference for single stranded over double stranded DNA with cleavage occurring at the first, second or third phosphodiester bond that is 5′ to the mismatch. |
