Subcloning Efficiency™ DH5α™ Competent Cells are a versatile strain of chemically competent cells that provide a transformation efficiency of > 1 x 106 cfu/µg plasmid DNA. Subcloning Efficiency™ DH5α™ Competent Cells are an economical solution for routine subcloning procedures or any application where the starting DNA is not limiting.

Features of Subcloning Efficiency™ DH5α™ Competent Cells:

• Designed for general, everyday use
• Contain genetic markers useful for general applications

Ideal for routine subcloning procedures
Subcloning Efficiency™ DH5α™ Competent Cells are recommended for routine subcloning of genes into plasmid vectors but are not suitable for the generation of cDNA libraries. These economical cells yield >1 x 106 transformants/µg control DNA per 50 µL reaction.

Flexible cloning capabilities
Subcloning Efficiency™ DH5α™ Competent Cells contain the following genetic markers resulting in these benefits:

lacZΔM15 for blue/white color screening of colonies on plates containing X-gal or Bluo-gal
recA1 ensures increased insert stability and prevents unwanted recombination
endA1 improves the yield and quality of plasmid DNA prepared from minipreps
• DH5α™ competent cells support replication of M13mp vectors but do not support plaque formation
