DNA Ligases

DNA ligase and RNA ligase enzymes are essential for repairing nucleic acids, ensuring accuracy and integrity in molecular biology applications. Our high-efficiency DNA ligase solutions, including T4 DNA ligase, are specifically designed for DNA end-joining reactions and ligation of cohesive or blunt-ended DNA fragments. These ligases play a vital role in critical processes such as DNA replication, repair, and recombination. Whether you’re performing cloning, sequencing, or gene editing, these enzymes offer optimized performance for precise, reproducible results. 
 
Our ligase enzymes deliver unmatched stability and activity across a variety of workflows. These enzymes are engineered to improve ligation reaction optimization, reducing errors and ensuring successful outcomes in both routine and complex applications. Designed for use in molecular cloning and other DNA manipulation techniques, our ligase enzymes streamline DNA end-joining reactions, improving efficiency and reducing hands-on time. Reliable ligation enzymes from QIAGEN can be confidently used in experiments that demand precision and accuracy at every step.
