Storage and StabilityMay be stored at 4°C for short-term only. For long-term storage, store at -20°C. Aliquots are stable for at least 6 months at -20°C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffe
Quality Control
Overdigestion AssayNo detectable change in the specific fragmentation pattern is observed after 160-fold overdigestion (10u/ug lambda DNA x 16 hours) with Mph1103I.
Ligation/Recutting AssayAfter 50-fold overdigestion (3u/ug DNA x 17 hours) with Mph1103I, more than 95% of the DNA fragments can be ligated at a 5'-termini concentration of 0.1uM. More than 95% of these can be recut.
Labeled Oligonucleotide (LO) AssayNo detectable degradation of a single-stranded and double-stranded labeled oligonucleotide was observed after incubation with10units of restriction endonuclease for 4 hours.
Blue/White Cloning AssayPUC57 was digested at a unique site with 10units of enzyme for 16 hours. After religation and transformation 0.3% of white colonies were detected.
