About Z-Competent™ E. Coli - Strain JM109

The Z-Competent™ E. Coli strains are premade, chemically competent cells for simple and highly efficient DNA transformation. Z-Competent™ E. Coli cells are made chemically competent by a method that completely eliminates the need for heat shocking and related procedures. For transformation, simply mix DNA with cells and then spread onto solid medium − Mix & Go! The premade Z-Competent™ cells are highly efficient (> 108 transformants / µg pUC19) and can be used for cloning, sub-cloning, PCR fragment cloning, library construction, etc. Premade Z-Competent™ cells are supplied as a pack of 10 convenient 100 µl/tube single use aliquots or in a 96-tube format with removable 8-tube strips for your high-throughput transformation needs.

Specifications

Format Either as a pack of ten 100 µl tube single use aliquots or as a 96-tube 50 µl format with removable 8-tube strips
Genotype F`[traD36 proA+B+ laclq ∆(lacZ)M15] ∆(lac-proAB) glnV44 (supE44) e14- (McrA-) thi gyrA96 (NalR) endA1 hsdR17(rk- mk+) relA1 recA1
Storage -70°C
Additional Information Partly restriction-deficient; good strain for cloning repetitive DNA (recA-). Suppresses many amber mutations when glutamine is available but not the S100 or S7 mutation of λ, e.g., λgt11. Can be used for M13 cloning/sequencing and blue/white screening.
