For simple, high efficiency transformations without heat shock and lengthy incubations.


  • Simple 20 Second Transformation: No heat shock! Just add DNA and spread on plate.
  • High Transformation Efficiencies: Achieve 108 - 109 per µg of plasmid DNA.
  • Versatile: Excellent for general cloning, blue-white screening, and plasmid isolation.


The Mix & Go! Competent Cells - DH5 Alpha are premade E. coli DH5 alpha competent cells for simple and highly efficient DNA transformation. These DH5 alpha competent cells are made chemically competent by a method that completely eliminates the need for heat shocking and related procedures. For transformation, simply mix DNA with cells and then spread onto solid medium − Mix & Go! The premade Mix & Go! competent cells are highly efficient (> 108 transformants/µg pUC19) and can be used for cloning, sub-cloning, PCR fragment cloning, library construction, etc.

The mechanisms of electrotransfection of mammalian cells were determined by observing the interaction of plasmid DNA (pDNA) with the cell membrane and internalization of the pDNA into the cell. The plasmid used in the study was amplified using Mix & Go E. coli Competent Cells, strain Zymo 5α, from Zymo Research, and labeled with a fluorescence dye to visualize pDNA binding and internalization. The authors found that efficient electrotransfection is dependent on the presence of divalent cations and endocytic pathways that can transport the pDNA across the membrane.

In the process of developing a protocol to facilitate real-time imaging of apoptotic cell membrane changes in live cells, researchers used the Mix & Go Z-competent E.coli strain Zymo 5α from Zymo Research for fast, high-efficiency transformations to express annexin B12 modified with fluorophores that fluoresce when bound to phosphatidylserine-containing membranes.
