- Colony counts for E. coli strains DH5α and C41 (DE3) transformed with the products of RF cloning and of QuickStep-Cloning and plated on agar plates supplemented with: (i) 50 μg/ml kanamycin and (ii) 50 μg/ml kanamycin and 1 mM IPTG. Transformation efficiency was determined based on concurrent transformation of 1 ng intact pET24a-HLTEV-p53 plasmid. Numbers in the brackets denote RFP-expressing colonies, as determined by visual inspection of the plates
