Reagents Needed for One Reaction

DirectPlate™ BL21(DE3) competent cell:  50 µlDNA (or pUC19 Control, 10 pg/µl):  1 µl

Storage

DirectPlate™  BL21(DE3) competent cells:  -80 ºCpUC19 control DNA:  -20 ºC

Genotype

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™ BL21(DE3) 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.

Comparison Testing

Intact Genomics has performed extensive comparison testing to prove our DirectPlate™ BL21(DE3) chemically competent cells have the highest transformation efficiency on the market.1019-12 1019-36
