Our Competent Cell Sampler includes two reactions of four chemically competent E. coli strains.
-One Shot® Mach1™ T1R, catalog #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.

-One Shot® OmniMAX 2 T1R cells, catalog #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.
