Product Description
Recombinant T4 DNA Ligase is an enzyme widely used in molecular biology for its ability to join DNA fragments together. Belonging to the DNA ligase family, this enzyme plays a vital role in the formation of phosphodiester bonds between adjacent DNA strands. With a molecular weight of approximately 68 kDa, Recombinant T4 DNA Ligase efficiently catalyzes the ligation of DNA fragments, making it a valuable tool in various genetic engineering applications. Its precise and reliable function makes it an indispensable asset in molecular biology research and DNA manipulation techniques.

Activity |
One Weiss unit is equivalent to circa 67 cohesive-end ligation units.• T4 DNA Ligase is strongly inhibited by NaCl or KCl if the concentration is > 200mM.• Ligation of blunt-ended and single-base pair overhang fragments requires about 50 times as much enzyme to achieve the same extent of ligation as cohesive-end DNA fragments. Blunt-end ligation may be enhanced by addition of PEG 4000 (10% w/v final concentration) or hexamine chloride, or by reducing the ATP concentration to 50µM.• To dilute T4 DNA Ligase that will subsequently be stored at –20°C, 50% glycerol storage buffer should be used; to dilute for immediate use, 1x T4 DNA Ligase reaction buffer can be used. |
