产品详情
- Direct replacements for standard cloning strains (e.g., DH5α™, DH10B™, JM109, TOP10, XL1-Blue, etc.)
- Optimized genetics for high yields: phage T1 resistant, endonuclease and recombination minus, blue/white screening-capable.
- Available in a range of high transformation efficiencies (5 × 109 to 4 × 1010 cfu/µg).
- Convenient packaging options.

Lucigen’s E. cloni competent cells share the most useful genetic elements of standard cloning strains like DH5α™, DH10B™, JM109, TOP10, etc. and directly replace them in cloning protocols. However, E. cloni electrocompetent cells incorporate a unique manufacturing technology that increases transformation efficiency, recombinant yields and reliability (Figures 1 and 2), while decreasing costs. These cells provide solutions for a wide range of applications at economical prices.
Choice of strain:
- E. cloni 10G Competent Cells. Library construction, cloning, subcloning, and plasmid isolation with or without blue/white screening.
- E. cloni 10GF′Competent Cells. Contain the F' plasmid for infection with M13 to produce ssDNA.
Choice of efficiency:
-
E. cloni 10G SUPREME Electrocompetent Cells > 4 × 1010 cfu/µg pUC DNA
SUPREME Cells have the highest transformation efficiency available from any supplier. Choose SUPREME Cells for the most demanding cloning situations, such as construction of large, high complexity libraries or cloning difficult targets, which require the greatest number of transformants possible. -
E. cloni 10G & 10GF´ ELITE Electrocompetent Cells > 2 × 1010 cfu/µg pUC DNA
ELITE Cells have twice the transformation efficiency compared to “ultra high efficiency” cells from other suppliers. ELITE Cells provide large numbers of transformants from hard-to-clone fragments or limited DNA at a lower price. -
E. cloni 10G CLASSIC Electrocompetent Cells > 5 × 109 cfu/µg pUC DNA
CLASSIC Cells are high efficiency cells with a substantially lower cost per reaction. These cells are the most economical choice for standard cloning and library construction. 10G CLASSIC Cells are available in larger package sizes for convenient use in higher volume cloning applications.
Custom Competent Cells
Bulk Lucigen cells or your strain of E. coli, made to the highest possible transfection efficiency with custom dispensing! See Custom Competent Cells page for detailed information.
Plasmid cloning. E. cloni 10G SUPREME Cells provide recombinant yields higher than the highest efficiency cells offered by a leading supplier (Figures 1 and 2)

Resources
Competent Cells include Control DNA and Recovery Medium, and are packaged as SOLOs (1 transformation per tube), DUOs (2 transformations per tube), or SixPacks (6 transformations per tube). Recovery Medium is also available separately. The specified transformation efficiencies are with pUC DNA, unless indicated otherwise.
PLEASE NOTE: Bulk quantities (10 times larger than the largest retail package size below) and/or custom packaging are available at very attractive prices for all Lucigen Competent Cells. Please contact Lucigen.
