Beskrivelse
T4 DNA Ligase catalyzes the formation of a phosphodiester bond between the 5'-phosphate and 3'-hydroxyl termini of adjacent nucleotides in double-stranded DNA or RNA with either cohesive or blunt ends. This reaction requires ATP as a cofactor. Additionally, T4 DNA Ligase can repair single-strand nicks in double-stranded DNA, double-stranded RNA, or DNA/RNA hybrids.

[Note]:
① High-concentration Premium T4 DNA Ligase combined with 2× Rapid Ligation Buffer significantly enhances the speed and efficiency of blunt-end ligation. Therefore, prolonged incubation (>10 minutes) is not recommended, as it may substantially reduce the transformation efficiency of the ligation products.
② The 10× T4 DNA Ligase Buffer does not contain PEG and is compatible with standard ligation protocols that do not specify the use of rapid ligation buffer.
Storage
This product should be stored at -25~-15℃ for 2 years.
