Highlights
• Active in Themo Scientific restriction enzyme, PCR, and RT buffers (when supplemented with ATP)
• Fast – sticky-end ligation is completed in 10 minutes at room temperature
• Supplied with PEG solution for efficient blunt-end ligationApplications
• Cloning of restriction enzyme generated DNA fragments
• Cloning of PCR products
• Joining of double-stranded oligonucleotide linkers or adaptors to DNA
• Site-directed mutagenesis
• Amplified fragment length polymorphism (AFLP)
• Ligase-mediated RNA detection (seeReference 3)
• Nick repair in duplex DNA, RNA or DNA/RNA hybrids
• Self-circularization of linear DNA.Notes
• Binding of T4 DNA Ligase to DNA may result in a band shift in agarose gels. To avoid this, incubate samples with 6X DNA Loading Dye & SDS Solution at 70°C for 5 min or 65°C for 10 minutes and chill on ice prior to electrophoresis.
• The volume of the ligation reaction mixture should not exceed 10% of the competent cell volume in the transformation process.
• Prior to electro-transformation, remove T4 DNA Ligase from the ligation mixture by spin column or chloroform extraction. The extracted DNA can be further precipitated with ethanol.
