Description

One Shot TOP10/P3 Chemically Competent E. coli cells are designed for vector transformation encoding the synthetic supF gene (tyrosine tRNA suppressor) and allow high-quality pCDM8, pcDNA1.1 plasmid, or any other supF-containing vector preparation.

One Shot TOP10/P3 Chemically Competent E. coli cells are designed for vector transformation encoding the synthetic supF gene (tyrosine tRNA suppressor) and allow high-quality pCDM8, pcDNA1.1 plasmid, or any other supF-containing vector preparation.

One Shot TOP10/P3 strain features
• P3 plasmid for selection of supF-containing plasmids
• Mutated endA1 gene for increased quality of plasmid DNA preparations
• recA1 for reduced occurrence of non-specific recombination in cloned DNA
• lacZΔM15 for blue/white color screening of recombinant clones

P3 Plasmid
The P3 plasmid is a low-copy-number, 60 kb plasmid that carries kanamycin, tetracycline and ampicillin resistance markers. The kanamycin gene is fully active and is used to select for cells carrying P3. Tetracycline and ampicillin genes carry amber mutations which render the genes inactive during normal growth and replication of the bacteria. Upon transformation of a vector carrying the suppressor F gene, the amber mutations in the tetracycline and ampicillin genes on the P3 plasmid are suppressed and the E. coli are resistant to these antibiotics.
