Intact Genomics (ig®) DirectPlate™ Competent cells offer simple, fast, and robust results for your DNA transformation needs. DirectPlate™  DH5-Alpha chemically competent E. coli cells are a perfect choice for researchers looking to simplify their transformation workflow by eliminating heat shock, lengthy incubations, and time-consuming outgrowth procedures. Simply mix and directly plate! DirectPlate™  DH5-Alpha chemically competent E. coli cells provide higher transformation efficiency than any competitor‘s similar product and are suitable for high-efficiency transformation in a wide variety of applications such as cloning and sub-cloning.

Transformation efficiency is tested by using the pUC19 control DNA supplied with the kit and using the high-efficiency transformation protocol. Transformation efficiency should be greater than 1×108 – 109 CFU/µg pUC19 DNA. Untransformed cells are tested for appropriate antibiotic sensitivity.
