T4 DNA Ligase – FL101

Rated 4.00 out of 5 based on 1 customer rating
(1 customer review)

Product Description

T4 DNA Ligase

T4 DNA Ligase catalyzes the formation of a phosphodiester bond between juxtaposed 5′-phosphate and 3′-hydroxyl termini in duplex DNA or RNA with blunt or cohesive end. The enzyme repairs single-strand nicks in duplex DNA, RNA or DNA/RNA hybrids but has no activity on single-strand nucleic acids. This DNA Ligase requires ATP as a cofactor.

Unit Definition

One unit is the amount of enzyme required to give 50% ligation of Hind III fragments of λ DNA (5 ́ DNA termini concentration of 0.12 μM, 200 μg/ml) in a total reaction volume of 20 μl in 30 minutes at 16°C in 1x T4 DNA Ligase Buffer.

Quality Control

Functional absence of endonucleases and exonucleases activities

Applications for T4 DNA Ligase

  • Cloning blunt-end or cohesive-end fragments.
  • Ligation of synthetic linkers or adaptors.

    Tried this T4 ligase as an alternative to the T4 Ligase that we nornally use. Ligation was a success!
