Digestion of Agarose-embedded DNA
A minimum of 5units of enzyme is required for complete digestion of 1ug of agarose-embedded lambda DNA in 16 hours.
Methylation Effects
Dam, Dcm, EcoKl: never overlaps - no effect
CpG may overlap - no effect
EcoBl: may overlap-effect not determined
Overdigestion Assay
No detectable change in the specific fragmentation pattern is observed after 160-fold overdigestion (10u/ug lambda DNA x 16 hours) with BpiI.
Blue/White Cloning Assay
The B/W assay was relpaced with L0 test after validating experiments showed L0 test ability to detect nuclease and phosphatase activities with sensitivity that equals to that of B/W test.
Labeled Oligonucleotide (LO) Assay
No detectable degradation of single-stranded or double-stranded labeled oligonucleotide occurred duringincubation with 10 units of Bpil for 4 hours.
Ligation/Recutting Assay
The ligation and recleavage assay was replaced with L0 test after validating experiments showed L0 test ability to trace nuclease and phosphatase activities with sensitivity that is higher than L/R by a factor of 100.
