  • Application
    Ligation (Lig)
    E.coli DNA Ligase is an NAD+-dependent enzyme that catalyzes the formation of a phosphodiester bond between cohesive 3'-hydroxyl and 5'-phosphoryl termini of double-stranded DNA (dsDNA). This enzyme is also active on nicked DNA but is not effective for the formation of DNA-RNA or RNA-RNA hybrids.
    Enzyme supplied with 10X Reaction Buffer
    Unit Definition
    One unit is defined as the amount of E. coli DNA Ligase that is required to give 50% ligation of HindIII-digested λ DNA in a total reaction volume of 20 μl in 30 minutes at 16°C in 1X E.coli DNA Ligase Reaction Buffer (concentration of 5' DNA termini is 0.12 μM [300 μg/ml]).
  • Comment

    • Ligation of dsDNA with cohesive termini
    • cDNA cloning of products from second strand cDNA synthesis experiments
    • Alternative to T4 DNA Ligase when bluntend ligation is not required
    • For ligation of bluntend fragments use T4 DNA Ligase (abm Cat. No. G467)

    For Research Use only
