Recommended 50 μl assay

Protocol:
Double Digestion - Buffer Compatibility:
B1 - <10 % Relative Activity
B2 - 25-50 % Relative Activity
B3 - 50-75 % Relative Activity
B4 - 100 % Relative Activity
B5 - 50 % Relative Activity
2x UB - 100 % Relative Activity (recommended)
Please note that the optimum digestion condition for this enzyme is 2x UB. Within the Universal Buffer (UB) system, the most majority of our enzymes display 100% Relative Activity in 1x UB and only few either in 0.5x or 2x UB. If optimum condition for second enzyme is different than the recommended for the first enzyme, we suggest carrying out first the restriction at the higher recommended concentration of UB and dilute the reaction volume to the adequate UB concentration for further proceeding with the second restriction.

Reaction Buffer Compatibility:
Our restriction enzymes are fully compatible to restrictases and buffer systems from other manufacturers and can be used along in double digestions. To obtain best results, consult the corresponding manuals of all involved products.
Ligation and recutting:
After 5-fold overdigestion with MspCI, >95% of the DNA fragments can be ligated and recut with this enzyme.
DNA Methylation:
No Inhibition: dam, dcm, CpG
Quality Control:
All preparations are assayed for contaminating endonuclease, 3'-exonuclease, 5' exonuclease/ 5' phosphatase, as well as nonspecific single- and doublestranded DNase activities.
