 | Source: Nocardia corallina.
Buffer supplied: 10x B3* (incl. 10x BSA).
Substrate for unit definition: λ DNA (4 sites).
Reaction conditions: 100 mM NaCl, 50 mM Tris-HCl (pH 7.9 @ 25°C), 10 mM MgCl2, 1 mM DTT, 0.02 % Triton X-100, 100 µg/ml BSA. Incubate at 37°C.
Storage buffer: 50 mM KCl, 10 mM Tris-HCl (pH 7.4), 0.1 mM EDTA, 1 mM dithiothreitol, 200 µg/ml BSA and 50 % glycerol. Store at -20°C. |  | Ligation and recutting: After ten-fold overdigestion with Nco I, >95 % of the DNA fragments can be ligated and recut with this enzyme.
Star activity: Conditions of high enzyme concentration, or glycerol concentration >5 % may result in star activity.
Heat inactivation: 65°C for 20 minutes. |  |
