Webby adding T4 DNA ligase (10 U), achieved at 25 C for 12 h, and terminated by heating the mixture at 65 C for 10 min. Cyclization in diluted Taq DNA ligase buffer. The 10 Taq DNA ligase buffer from the commercial source was simply diluted by water, and used for the reactions. Otherwise, all the procedures were exactly the same as those ... WebT7 DNA Ligase is also active in buffers without PEG 6000, such as our T4 DNA Ligase Buffer and NEBuffer r1.1–r4.1, for applications in which PEG 6000 is detrimental. Please remember to supplement the reaction with 1 mM ATP (final concentration). Using these buffers, the activity of T7 DNA Ligase is reduced approximately 10-fold. ...
Substrate specificity and mismatch discrimination in DNA ligases
WebApr 14, 2024 · The products were ligated with T4 DNA ligase (TaKaRa, Dalian, Liaoning, China) at 16 °C o/n. The recombinant plasmids were confirmed by Sanger sequencing (Sangon Biotech, Shanghai, China) and co-transfected with pRL-TK plasmid (Renilla luciferase). After 24 h incubation, luciferase activities were measured with Dual … WebFAQ. Thermo Scientific T4 DNA Ligase catalyzes the formation of a phosphodiester bond between juxtaposed 5'-phosphate and 3'-hydroxyl termini in duplex DNA or RNA. The enzyme repairs single-strand nicks in duplex DNA, RNA, or DNA/RNA hybrids. It also joins DNA fragments with either cohesive or blunt termini, but has no activity on single ... clover patch silhouette
