Description:
DH5a is the most frequently used E.Coli strain for routine cloning applications. In addition to supporting blue/white screening recA1 and endA1 mutations in DH5a increase insert stability and improve the quality of plasmid DNA prepared from minipreps.

Application:

  • Highest transformation efficiency
  • General cloning
  • Blue-white selection
  • Plasmid isolation
