General Guidelines
Follow these guidelines when using ig™ 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 tapping the tube gently. Do not mix cells by pipetting or vortexing.


    • Remove competent cells from the -80 °C freezer and thaw completely on wet ice (10-15 minutes).
    • Aliquot 1-5 µl (1 pg-100 ng) of DNA to the chilled microcentrifuge tubes on ice.
    • When the cells are thawed, add 50 µl of cells to each DNA tube on ice and mix gently by tapping 4-5 times. For the pUC19 control, add 1 µl of (10 pg/µl) DNA to a chilled microcentrifuge tube, prior to adding 50 µl of cells. Mix well by tapping.
    • Incubate the cells with DNA on ice for 30 minutes.
    • After 30 minute ice incubation, heat shock the cells at 42 °C for 45 seconds.
    • Transfer the tubes to ice for 2 minutes.
    • Add 950 µl of Recovery Medium or any other medium of choice to each tube.
    • Incubate tubes at 37 °C for 1 hour at 210 rpm.
    • Spread 50 µl to 200 µl from each transformation on Pre-warmed selection plates.
    • Incubate the plates overnight at 37 °C.
