Descripción
T7 Endonuclease I is encoded by gene 3 of bacteriophage T7. It recognizes and cleaves mismatched DNA, cruciform DNA structures, Holliday junctions (four-way DNA junctions), heteroduplex DNA, and also cleaves nicked double-stranded DNA at a slower rate. Cleavage occurs at the first, second, or third phosphodiester bond on the 5′ side of the mismatched base.
Features
High Cleavage Activity: 20 U of T7 Endonuclease I efficiently cuts 200 ng of mismatched dsDNA.
High Protein Purity: ≥95% (as determined by SDS-PAGE).

Figure 1. Verification of T7 Endonuclease I cleavage performance (Input: 200 ng DNA)
Yeasen T7 Endonuclease I and imported Supplier A* T7 Endonuclease I were incubated with mismatched dsDNA substrates and analyzed by agarose gel electrophoresis. The results show that 20 U of Yeasen T7 Endonuclease I efficiently cleaves 200 ng of mismatched dsDNA, with a cleavage performance comparable to that of Supplier A*.
