Thermus aquaticus Cc1331

Restriction Enzyme Buffer E, 10X; R1625-04, Included: 10mM Tris-HCl (pH 8.5), 10mM MgCl2, 100mM KCl and 0.1mg/ml BSA. Incubate at 65C**

Diluent Buffer:
Dilute with 10mM Tris-HCl (pH 7.4 at 25C), 100mM KCl, 1mM EDTA, 1mM DTT, 0.2mg/ml BSA and 50% glycerol.

Storage Buffer:
Supplied as a liquid in 10mM Tris-HCl (pH 7.5 at 25C), 100mM KCl, 1mM DTT, 0.1mM EDTA, 0.2mg/ml BSA and 50% glycerol.
Overdigestion Assay:
No detectable change in the specific fragmentation pattern is observed after 160-fold overdigestion (10u/ug lambda DNA x 16 hours) with TaiI.

Ligation/Recutting Assay:
After 50-fold overdigestion (3 units/ug DNA x 17 hours) with TaiI, more than 95% of the DNA fragments can be ligated at a 5'-termini concentration of 1.5uM. More than 95% of these can be recut.

Labeled Oligonucleotide (LO) Assay:
No detectable degradation of a single-stranded and double-stranded labeled oligonucleotide was observed after incubation with 10 units of restriction endonuclease for 4 hours.

Methylation Effects:
TaiI does not cut Am5CGT. Blocked by CG methylation.

Stability during Prolonged Incubation:
A minimum of 0.3 units of enzyme is required for complete digestion of 1ug of lambda DNA in 16 hours at 65C.

Thermal Inactivation:
Enzyme is not inactivated by incubation at 80C for 20min.

Compatible Ends:

Number of Recognition Sites in DNA:
