Instruction Manual
NoteChemically Z-Competent™ cells are stable for 6 months at < -70oC. Reagents are routinely tested on a lot-to-lot
basis to ensure they provide maximal performance and reliability. Product Description

Z-Competent™ E. coli are premade chemically competent cells used for simple
and highly efficient DNA transformation. Z-Competent™ E. coli cells are made chemically competent by a unique method using ZymoBroth™ that completely
eliminates the need for heat shock and related procedures. For transformation, DNA can be added directly to Z-Competent™ cells and the mixture spread directly to a culture plate - Mix & Go! Transformation efficiencies typically range from 108–109 transformants/µg of pUC19 DNA (see figures below), which make the cells optimal for cloning, sub-cloning, library construction, etc. Premade Z-Competent™ cells are supplied as a pack of 10 convenient 100 µl/tube aliquots or in a 96-well format (12x8- Z-Competent™ E. coli cells prepared with ZymoBroth™ display fast transformation kinetics and high
transformation efficiencies. Figures above show the transformation kinetics for Z-Competent™ JM109 and BL21
strains of E. coli generated using ZymoBroth™ and SOB growth media. Plasmid DNA (pUC19) was used for transformation and the data are the averages of three individual experiments.

Incubate on ice for 2-5 minutes (maximum 60 minutes). 3. Spread 50-100 µl onto a pre-warmed culture plate.

Note: The procedures above are for plasmids containing Ampicillin resistant markers. If Kanamycin, Tetracycline,
Chloramphenicol, Erythromycin or any non-lactamase selection markers are used, an outgrowth step is required
prior to plating. (see Notes Section 4 on page 3 regarding Outgrowth)
Important! Since chemically competent cells are extremely sensitive to changes in temperature,
transformation should be performed immediately after thawing. The cells should avoid being
exposed to room temperature for more than a few seconds. To mix cells after DNA addition,
gently tap the tube with your fingers and then shake the tube downwards in a single motion from
the elbow to collect the mixture at the bottom of the tube. Avoid repeated pipetting. Immediately
transfer the transformation mixture(s) to ice or an ice bath (0oC).
Fast Transformation of Z-Competent™ Cells* - Mix & Go!

1. Add 1-5 µl plasmid DNA to a tube of thawed Z-Competent™ cells on ice, mix gently for a few seconds (try to keep the added volume of DNA less than 5% of the total). 2. Spread 50-100 µl of the mixture onto a pre-warmed (37°C) culture plate containing Ampicillin. Incubate the plate at the appropriate temperature (e.g., 37°C) for the colonies to grow. *For Ampicillin selection only. For selection with other antibiotics, see Notes Section 4 on page 3.

1. E. coli Strains
Different E. coli strains vary in their ability to be transformed with DNA. Strains like JM109, C600, TG1, and DH5a* typically yield the highest transformation efficiencies. 2. Incubation Time
The “Mix & Go!” procedure (page 2) will work for most transformations using Ampicillin selection and not requiring outgrowth (see Section 4 below). The highest transformation efficiencies can be obtained by incubating Z-Competent™ cells with DNA on ice for 2-5 minutes (60 minutes maximum) prior to plating. 3. Prewarming Culture Plates
Chilled plates will decrease Z-Competent™ cell transformation efficiency. It is recommended that culture plates be pre-warmed to >20°C (preferably 37°C) prior to 4. Addition of SOC Medium to Transformation Mixtures (Outgrowth)
When selecting with Kanamycin, Tetracycline, etc., an outgrowth performed in SOC medium is required for efficient transformation. In most cases, this step can be omitted when selecting with Ampicillin. After the transformation mixture has incubated on ice for 5-10 min, add 4 volumes of SOC (400 µl of SOC to 100 µl of transformation mixture) and incubate for 1 hour at 37 300 rpm. Afterwards, spread the mixture directly onto pre-warmed culture plates. Reducing agents [e.g., DTT (Dithiothreitol) and 2-ME (β-mercaptoethanol)] are not Appendix
