Mix & Go E. coli are premade chemically competent cells used for simple and highly efficient DNA transformation. Mix & Go E. coli cells are made chemically competent by a unique method that completely eliminates the need for heat shock and related procedures. For transformation, DNA can be added directly to Mix & Go competent cells and the mixture spread directly to a culture plate - Mix & Go! Transformation efficiencies typically range from 108-109 transformants/µg of pUC19 DNA (see figures below), which make the cells optimal for cloning, sub-cloning, library construction, etc. Premade Mix & Go competent cells strain Zymo 10B are supplied as a pack of 10 convenient single use aliquots or as a 96-well rack with removable 8-tube strips for your high-throughput transformation needs.
