Quality Control

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.

General Guidelines

Follow these guidelines when using DirectPlate™  10B chemically competent E. coli.

  • Handle competent cells gently as they are highly sensitive to changes in temperature or mechanical lysis caused by pipetting.
  • Thaw competent cells on ice, and transform cells immediately following thawing. After adding DNA, mix by gently pipetting up and down a few times. 1013-13 1013-36
