TG1 Electrocompetent Cells, 24 Rxns (DUOs)Construct larger, more complex phage display libraries with highest efficiency cells. This amber suppressor strain can be used for phage display and protein expression.Perfect for antibody phage display or peptide phage display library creation. The highest efficiency TG1 competent cells available: 4 10^10 cfu/ug. TG1 Electrocompetent Cells have an amber suppressor strain (supE) prepared as highly efficient electrocompetent cells for phage display library screening. These cells are used for phage display and protein expression.
