Includes: Competent Cell Sampler contains two transformations each of four strains of chemically competent cells in One Shot™ format.



  • One Shot™ Mach1™ T1R, (Cat. No. C862003), is the fastest-growing chemically competent strain currently available. Mach1™ T1R colonies are clearly visible within eight hours of plating your transformation. From an overnight colony, minipreps can be performed after four hours of growth.
  • Genotype: F- φ80(lacZ)ΔM15 ΔlacX74 hsdR(rκ–, mκ +) ΔrecA1398 endA1 tonA
    • One Shot™ OmniMAX 2 T1R cells, (Cat. No. C854003), are perfect for use in all cloning applications, including Gateway™ technology. They offer the highest transformation efficiency of any chemically competent cell in the One Shot™ packaging format.
