One Shot® TOP10F´ Chemically Competent E. coli are identical to TOP10 cells, with the addition of an F´ episome. TOP10 competent cells are provided at a transformation efficiency of 1 x 109 cfu/µg supercoiled DNA and are ideal for high-efficiency cloning and plasmid propagation.

Using One Shot® TOP10F´ Chemically Competent E. coli
The F´ episome carries the tetracycline resistance gene and allows isolation of single-stranded DNA from vectors that have an f1 origin of replication. In addition, the F´ episome carries the lacIq repressor for inducible expression from trc, tac, and lac promoters using IPTG. TOP10F´ cells require IPTG induction for blue/white color screening.
