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 (> 10^8 transformants/µg pUC19) and can be used for cloning, sub-cloning, PCR fragment cloning, library construction, etc.
