AluI is a restriction enzyme that recognizes AG^CT sites.
10X Cutting Buffer is included that contains BSA, which enhances enzyme stability and binds to contaminants in DNA preps.
Product Details
Source: | Produced in an E. coli strain that carries the cloned AluI gene from Arthrobacter luteus. |
|
Concentration: | AluI 10,000 units/ml
Includes 10X Cutting Buffer |
|
Formulation: | Liquid. In 100mM KCl, containing 10mM Tris-HCl, pH 7.4, 1mM DTT, 0.1mM EDTA, 50% glycerol and 200µg/ml BSA.
After reconstitution, 1X Cutting Buffer: 50mM potassium acetate, 20mM Tris-acetate, 10mM magnesium acetate, 100µg/ml BSA, pH 7.9, at 25°C. |
|
Quality Control: | Exonuclease Activity (Radioactivity Release):
A 50 µl reaction in 1X Cutting Buffer containing 1 µg of a mixture of single and double stranded [3H] E. coli DNA and a minimum of 30 units of AluI incubated for 4 hours at 37°C releases <0.1% of the total radioactivity.
Ligation and Recutting (Terminal Integrity):
After a 10-fold over digestion of λ DNA with AluI, ~75% of the DNA fragments can be ligated with T4 DNA ligase in 16 hours at 16°C. Of these ligated fragments, >95% can be recut with AluI.
Non-Specific DNase Activity (16 Hour):
A 50 µl reaction in 1X Cutting Buffer containing 1 µg of λ DNA and a minimum of 50 Units of AluI incubated for 16 hours at 37°C results in a DNA pattern free of detectable nuclease degradation as determined by agarose gel electrophoresis. |
|
Activity: | One unit is defined as the amount of enzyme required to digest 1µg of λ DNA in 1 hour at 37°C in a total reaction volume of 50µl. |
