TOPO™ TA Cloning™ Dual Promoter kits are for fast, efficient cloning and subsequent in vitro transcription. These kits include the pCR™II-TOPO™ TA vector with dual T7 and SP6 promoters. By eliminating time-consuming and tedious restriction site cloning, TOPO™ cloning is the most reliable method, featuring a 3-step protocol and 5-minute cloning reaction, and yielding up to 95% recombinants.
Convenient features of this TOPO™ TA Cloning™ Dual Promoter kit include: • 3´-T overhangs for direct ligation of Taq-amplified PCR products • T7 and SP6 promoters for efficient in vitro transcription • M13 forward and reverse primer sites for sequencing • 16 convenient restriction sites, including EcoRI, flanking your insert for subsequent excision or subcloning • Kanamycin and ampicillin resistance for your choice of selection in E. coli • Easy blue/white colony screening for selection of recombinants • No competent cells included for flexibility and cost-savings
