DNA ligation kits, quick

DNA Ligation Kit, Version 1 and DNA Ligation Kit, Version 2.1 enable high-efficiency ligation of DNA molecules in vitro. Using an optimized buffer system and T4 DNA Ligase, these DNA ligation kits offer fast ligation in 30 minutes. Ligation reactions can be used directly in selected bacterial transformations with no need for DNA purification.

DNA Ligation Kit, Version 1 and DNA Ligation Kit, Version 2.1 provide the fliexibility of formats, with the DNA Ligation Kit, Version 2.1 containing a convenient premix of enzyme and buffer that further minimizes pipetting steps and permits small final reaction volumes (for standard reactions). By using Solution II of the DNA Ligation Kit, Version 2.1, linker ligation may also be performed. Transformation efficiency can be further improved by the addition of Solution III (Transformation Enhancer) into circular ligation reactions prior to transformation. The DNA Ligation Kit, Version 1.0 can be used for DNA concatenation via the addition of Solution B alone.

Takara's DNA Ligation Kits are simple, two-component systems that allow rapid performance of all cloning procedures requiring the covalent joining of DNA molecules in vitro. Using an optimized buffer system and T4 DNA Ligase, these kits allow ligation in 30 minutes with high transformation efficiency. For general ligation reactions, these kits allow good efficiency in only 3 minutes. The reactions can be used directly in some bacterial transformations without DNA purification. The kits have similar, simple procedures and give nearly equivalent transformation efficiencies. Version 1.0 can be used for DNA concatenation using Solution B alone.

Control insert DNA (plasmid vector) digested with EcoR I was ligated into dephosphorylated lambda gt11/EcoR I arms for 3 minutes at 25°C. Back Efficiency of Linker Ligation Efficiency of Linker Ligation. A pBgl II linker d[pCAGAATCTG] was ligated with dephosphorylated Hinc II pUC118 DNA. Ten nanograms of the ligation reaction was transformed into E. coli JM109 Competent Cells (1.3 x 10⁸ transformants/µg DNA), and the transformation efficiency was calculated from the yield of white colonies.
