T4 DNA Ligase (Fast) [5U/uL]

T4 DNA Ligase(Fast) is produced by E.coli carrying T4 bacteriophage gene 30. The enzyme catalyzes the formation of phosphodiester bonds between 5'-phosphate groups and 3'-hydroxyl groups of double-stranded DNA or RNA. It can repair single-strand nicks in double-stranded DNA, RNA, or DNA/RNA hybrids and can ligate DNA fragments with sticky or blunt ends. It is not active on single-stranded nucleic acids. The enzyme is primarily used for cloning of restriction endonuclease-digested DNA fragments, site-directed mutagenesis, cloning of PCR products, linear DNA circularization, and repair of double-stranded DNA nicks. T4 DNA Ligase (Fast) requires ATP as a cofactor and completes sticky end ligation reactions at room temperature in just 10 minutes.
