NEB_C2925H
Methyltransferase deficient chemically competent E. coli cells suitable for growth of plasmids free of Dam and Dcm methylation. Note that dam- strains are not recommended as a host for primary cloning/ligation. The dam mutation can result in an increased mutation rate in the cell and a reduction in the transformation efficiency. DNA should be maintained in a dam+ strain unless there is a specific need for DNA free of Dam or Dcm methylation.
Highlights
- Grow plasmids free of Dam and Dcm methylation
- Free of animal products
- Phage T1 resistant (fhuA31)
- Activity of nonspecific endonuclease I (endA1) eliminated for highest quality plasmid preparations
- K12 Strain
Transformation Efficiency
1-3 x 106 cfu/μg pUC19 DNA
