Enzyme PropertiesMethylation Effects:
Dam, Never overlaps - no effect
Dcm: Never overlaps - no effect
CpG: May overlap - cleavage impaired

Overdigestion AssayNo detectable change in the specific fragmentation pattern is observed after a 160-fold overdigestion with Bst1107I (10U/ug lambda DNA x 16 hours).
Ligation and Recleavage (L/R) AssayThe ligation and recleavage assay was replaced with LO test after validating experiments showed LO test ability to trace nuclease and phosphatase activities with sensitivity that is higher than L/R by a factor of 100.
Labeled Oligonucleotide (LO) AssayNo detectable degradation of single-stranded or double- stranded labeled oligonucleotides occurred during incubation with 10 units of Bst1107I for 4 hours.
Blue/White Cloning AssayThe B/W assay was replaced with L0 test after validating experiments showed L0 test ability to detect nuclease and phophatase activities with sensitivity that equals to that of B/W test.
Storage and StabilityMay be stored at 4°C. For long-term storage, aliquot and store at -20°C. Aliquots are stable for 6 months after receipt. For maximum recovery of product, centrifuge the original vial prior to removing the cap. Further dilutions can be made in assay buffer.
