T4 dna ligase mechanism
WebLigation in the laboratory is normally performed using T4 DNA ligase. It is broadly used in vitro as molecular biology research tool due to its capability of joining as sticky as blunt DNA ends. [2] However, procedures for ligation without the … WebT4 DNA ligase-catalyzed cyclization reactions (50 or 100 μL) are performed at 22°C with 30-nM DNA restriction fragment (with or without various concentrations of added HMGB protein), ligation buffer (20-mM Tris–HCl, pH 8.0, 30-mM KCl, 100-μg/mL BSA, 1.8-mM ATP, 10-mM MgCl2), and T4 DNA ligase [final concentrations of 50 U/mL (DNA alone) or 20 …

Did you know?
WebT4 DNA ligase is an ATP-dependent ligase that catalyzes a joining reaction between DNA molecules. By joining the 3’-hydroxy and 5’-phosphate termini to form a phosphodiester, DNA ligases are absolutely essential for DNA replication and repair in all organisms. WebHerein, an efficient pair of split G-quadruplex probes was selected (S/N = 21) to construct a simple, rapid and label-free technique for the detections of T4 DNA ligase and PNK = 21) to construct a simple, rapid and label-free technique for …
