Supplied With
R1625: Restriction Enzyme Buffer A, 10X; (1X compostition after dilution)-33mM Tris-acetate, pH 7.9, 10mM magnesium acetate, 66mM potassium acetate, 0.1mg/ml BSA.
Blue/White Cloning Assay
The mix of pUC57/HindIII, pUC57/Eco32I and pUC57/PstI digests was incubated with 10 units of enzyme for 16 hours. After religation and transformation 0.2% of white colonies were detected.
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.

Ligation/Recutting Assay
After 50-fold overdigestion (3u/ug DNA x 17 hours) with XagI, approximately 80% of the DNA fragments can be ligated in the reaction mixture containing 20-40u of T4 DNA Ligase/1ug of fragments and 10% of PEG at a 5'-termini concentration of 0.1µM. More than 95% of these can be recut.
Overdigestion Assay
No detectable change in the specific fragmentation pattern is observed after 320-fold overdigestion (20u/ug lambda DNA x 16 hours) with XagI.

Product Notes
The XagI (Catalog #AAA638360) is a Restriction Enzyme produced from Xanthobacter agilis Vs18-132 and is intended for research purposes only. The product is available for immediate purchase. It is sometimes possible for the material contained within the vial of "XagI, Restriction Enzyme" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.Precautions
