產品簡介

DH5α Competent Cells

詳細介紹

Thermo Scientific DH5α Competent Cells are high efficiency, chemically competent E. coli cells ideal for construction of gene banks or generation of cDNA libraries using plasmid-derived vectors. 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

Applications
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
