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.
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. High efficiency (> 109 cfu/μg).
