Protein Tag His Tag (6X), V5 Epitope Tag

  • Proofreading enzyme is used: fewer errors in cloned genes
  • Greater than 90% of clones are in correct orientation for expression, reducing time spent screening colonies for clone orientation
  • CMV promoter: high expression levels
  • C-terminal V5-His fusion tag for easy detection of recombinant protein with an Anti-V5 Antibody
  • 6xHis tag for rapid protein purification on nickel-chelating resin
