Description

Description

Subcloning Efficiency DH5α Competent Cells are a versatile, chemically competent strain for cloning that provides 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 general application where DNA for transformation is not limiting.

Features of Subcloning Efficiency DH5α Competent Cells
• Designed for general, low throughput, everyday use
• Standard laboratory strain useful for general cloning applications

Ideal for routine subcloning procedures
Subcloning Efficiency DH5α Competent Cells are recommended for routine subcloning of genes into plasmid vectors. 500 μL of chemically competent cells are pre-aliquoted in tubes for ten reactions using 50 μL. These cells yield >1 x 106 transformants/μg control DNA per 50 μL reaction. Subcloning Efficiency DH5α Competent Cells are not suitable for the generation of cDNA libraries.

Flexible cloning capabilities
Benefits of Subcloning Efficiency DH5α Competent Cells include:
• lacZΔM15 for blue/white color screening of colonies on plates containing X-gal or Bluo-gal
• recA1 that ensures increased insert stability and prevents unwanted recombination 
• endA1 that improves the yield and quality of plasmid DNA prepared from minipreps
• Supports replication of M13mp vectors but not plaque formation
