Supplier:  Thermo Scientific™ EC0112

Catalog No. FEREC0112

Description

• The φ80dlacZΔM15 marker provides α-complementation of the β-galactosidase gene from pUC or similar vectors to allow blue/white colony screening on bacterial agar plates containing Bluo-Gal or X-Gal
• RecA1 and endA1 mutations in DH5α cells improve insert stability and quality of the extracted plasmid DNA
• High transformation efficiency: >1x109 cfu/μg pUC19 DNA
• Suitable for routine and high-throughput cloning applications
• Genetic markers that allow for blue/white colony screening
• Convenient two reactions per vial packaging
• S.O.C. Outgrowth medium included
• DH5α Competent Cells are suitable for variety of applications requiring high transformation efficiency:
  • Efficient DNA cloning derived from PCR, cDNA-generation reactions
  • recA1 marker facilitates working with difficult to transform DNA
  • Ideal for generation of cDNA libraries using plasmid-derived vectors
  • Site-directed mutagenesis
