Competent Cells
Range of Chemically and Electrocompetrent cells for your molecular cloning needs
Overview of the range
CopyCutter™ EPI400™ Electrocompetent and Chemically Competent E. coli
Highly stable and competent cells for unstable DNA and keeping low copy numbers
CopyCutter™ EPI400™ E.coli* cells were developed to significantly lower the copy number of a wide variety of common vectors so that you can more readily clone unstable DNA sequences. DNA that is unstable at high-copy number often codes for a protein that inhibits cell growth or contains AT- and GC-rich sequences or sequences with strong secondary structure. The CopyCutter™ EPI400™ cell line was derived from our high-transformation efficiency phage T1-resistant TransforMax™ EC100™ E. coli strain by manipulating a gene that controls the copy number of vectors containing ColE1 or pMB1 origins of replication (e.g., pUC- and pET-type vectors).
