• Clone with speed and efficiency
• Transform into E. coli without clean-up or desalting

Applications Blunt-end and TA cloning of PCR products. Ligation of next-gen sequencing adaptors to blunt-ended DNA. Genomic DNA cloning and subcloning. BAC/fosmid library construction. cDNA cloning. Linker ligation. The Fast-Link™ DNA Ligation Kit uses a high-quality ligase (Fast-Link T4 DNA Ligase), that was cloned at Epicentre and formulated to provide extremely rapid, high-efficiency DNA ligation. Cohesive-end ligations can be performed in 5 minutes at room temperature. In contrast to other ligases, it is not necessary to desalt Fast-Link ligation reactions prior to transformation of electrocompetent or chemically competent cells. The Fast-Link Kit can be used for routine and high-throughput DNA cloning.

Benefits

• Cohesive-end ligations in 5 minutes at room temperature (Fig. 1).
• Blunt-end ligations in 15 minutes at room temperature (Fig. 2).
• Ligation of PCR product with A-overhangs in 1 hour at 16°C.
• High ligation efficiency (Table 1).
• Desalting of ligation products is not needed prior to transformation of electrocompetent or chemically competent cells.
• BAC ligation with inserts >100 kb can be performed in 4 hours, instead of overnight reactions as with other ligases.
