一般描述
Sigma′s DNA Ligation Kit contains all of the reagents necessary to perform DNA ligation reactions at room temperature using blunt or sticky ends. This kit replaces previous workflows requiring cooking steps and long incubations. Pre-made buffers allow for fast & easy setup.
应用
QuickLink™ DNA Ligation Kit has been used for the ligation of pGL2-basic luciferase-reporter plasmid with vascular endothelial growth factor (VEGF) promoter sequence and for the ligation of NLR family caspase activating and recruitment domain (CARD)-containing protein 4 (Nlrc4) promoter with the luciferase plasmid vector pGL4.10-luc2
The QuickLink™ DNA Ligation Kit is suitable for:
- Joining blunt or cohesive-end fragments of DNA into a cloning vector
- Recircularization of linear DNA
- Formation of concatamers
- dsDNA nick repair
生化/生理作用
One of the most important steps in the cloning process is the ligation of linear DNA into a cloning vector. DNA ligations are performed by incubating DNA fragments with appropriately linearized cloning vectors in the presence of buffer, ATP, and DNA ligase. Many parameters affect ligations such as the relative ratio of insert to vector, the quality and type of the DNA ends, the temperature of ligation and the concentration of DNA.
特点和优势
- Fast 5 minutes ligation
- High ligation efficiency
- Room temperature reactions – no cooling required
- Perform bacterial transformation with the reaction mixture

ATP-dependent DNA ligases are essential enzymes in both DNA replication and DNA repair processes. Here we report a functional characterization of the T4 DNA ligase. One N-terminal and two C-terminal deletion mutants were expressed in Escherichia coli as histidine- tagged

Polyethylene glycol (PEG) stimulates ligation with T4 DNA ligase. In 10% (w/v) PEG 6,000 solutions, only intermolecular ligation is enhanced by monovalent cations, while both inter- and intramolecular ligation occur without their presence. Similar stimulation was also caused by divalent

Synaptic vesicles isolated from sheep brain cortex exhibit an ATP-dependent Ca2+ accumulation that is inhibited by the protonophore uncoupler carbonyl cyanide m-chorophenylhydrazone (CCCP) and completely released by the Ca2+ ionophore ionomycin. This transport activity was sensitive to the V-type ATPase
实验方案
T4 DNA ligase is used for the joining of DNA molecules with compatible cohesive (sticky) termini, joining of blunt ended double stranded DNA molecules
