For DNA amplification, I grow my cells in an Ampicillin+Tetracyclin culture plate. The cells used are XLBlue cells and during inoculation in LB, I add about 20uL of Amp and 25uL of Tetracyclin in a 10mL LB. For purification, Promega kit is used.
Are there any suggestions or insights you can provide to help address this problem
