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 cells and the mixture spread directly to a culture plate. Transformation efficiencies typically range from 108-109 transformants/g of pUC19 DNA , which make the cells optimal for cloning, sub-cloning, library construction, etc. Premade Mix & Go cells are supplied as a pack of 10 convenient 100 l/tube aliquots or in a 96-well format (12 x 8 - tube strips) of 50 l/tube.
