Product Overview

Description

T7 Endonuclease I, a stable homodimer of identical 149 amino acid subunits (1) is the product of a recombinant gene in E. coli . Double-stranded breaks (DSBs) generated by CRISPR/TALEN at desired target sites can be PCR-amplified, and the PCR products can be denatured and re-annealed to form mismatched DNA. If the mismatched DNA length position is more than 1 bp, T7 endonuclease I can recognize and cleave it. It is useful for quantitatively estimating the nuclease-induced mutation frequency of gene edited cells.

 Applications

  • Resolve four-way junction or branched DNA
  • Detect or cleave heteroduplex and nicked DNA
  • Randomly cleave linear DNA for shot-gun cloning

Protein purity
The physical purity of this enzyme is ≥99% as assessed by SDS-PAGE with Coomassie® blue staining.

Product Source
E coli BL21 (DE3) pLysS strain expressing T7 Endonuclease I gene.
