Web12 apr. 2024 · Cells were then made electrocompetent by four consecutive wash steps in chilled 10% (v/v) glycerol solution, which concentrated cells ~ 100-fold. On ice, 5 μL (250 ng) of the synthetic DNA cassette were added to 50 μL of electrocompetent cells and cells were electroporated (1.8 kV, 1 mm gap, BTX Gemini X2). WebTherefore, TG1 electrocompetent cells are considered an ideal selection for gene introduction in large phage libraries (Clackson, Hoogenboom, Griffiths, & Winter, 1991). The transformation efficiency of TG1electrocompetent cells was influenced by DNA amount, cell growth stage, field strength, and recovery time (Chen, Guo, Xie, & Shen, 2001 ). highlander apartments kennewick washington
