 Host    Escherichia Colilambda lysogen NM 989
Section Bar
 Form/Format    (167,000 U/ml) 50mM Tris-HCl (pH 7.8 at 25C), 10mM MgCl2, 10mM DTT, 1mM ATP, 25 ug/ml BSA and DNA (0.1 to 1 um in 5 termini).

Optimal ligation occurs at 16C.
Section Bar
 Physical Appearance    Sterile filtered liquid formulation
 Storage Buffer    50mM KCI, 10mM Tris-HCI (pH 7.4),0.1 mM EDTA, 1mM DTT, 200 ug/ml BSA and 50% glycerol. Store at -20C.
 Unit Definition    1. One unit is defined as the amount of enzyme required to give 50% ligation of Hind III fragments of DNA (5 DNA termini concentration of 0.12 uM, 300- g/ml) in a total reaction volume of 20 ul in 30 minutes at 16C in 1X T4 DNA Ligase Reaction Buffer.

2.One Weiss unit is defined as the amount of enzyme required to catalyze the exchange of 1 nmol of 32P from pyrophosphate to ATP, into Norit-adsorbable material in 20 minutes at 37C.
 Biological 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 50uM.
To dilute T4 DNA Ligase that will subsequently be stored at 20C, 50% glycerol storage buffer should be used; to dilute for immediate use, 1x T4 DNA Ligase reaction buffer can be used.
 Heat Inactivation    T4 DNA Ligase can be inactivated by incubation at 65C for 10 minutes.
 Quality Control    Purified free of contaminating endonucleases and exonucleases. Each lot of T4 DNA ligase is also tested in a mock cloning assay, which reveals any damage to the ligated DNA termini. Greater than 99.9% of the termini remain undamaged in this assay.

Exonuclease Activity:

Incubation of a 50l reaction containing 13,000 units of T4 DNA Ligase with 1g of a mixture of single and double-stranded [3H] E. coli DNA (200,000 cpm/ug) for 4 hours at 37C released < 0.3% of the total radioactivity.

Endonuclease Activity:

Incubation of a 50l reaction containing 13,000 units of T4 DNA Ligase with 1g of X174 RF I DNA for 4 hours at 37C resulted in < 5% conversion to RFII as determined by agarose gel electrophoresis.

Nuclease Activity :

Incubation of 13,000 units for 18 hours in assay buffer (without ATP) with Hind III fragments of gamma DNA yielded a clear and sharp banding pattern on agarose gels.
Section Bar
 Preparation and Storage    Two years when stored at -20C, 2 weeks at 4C.
 Other Notes    Small volumes of T4 DNA recombinant protein vial(s) may occasionally become entrapped in the seal of the product vial during shipment and storage. If necessary, briefly centrifuge the vial on a tabletop centrifuge to dislodge any liquid in the container`s cap. Certain products may require to ship with dry ice and additional dry ice fee may apply.
