Digestion Protocols

Double Digestions

4 hour incubation (37°C)

We used serial digestions to improve SpeI efficiency since it wasn’t working correctly as follows:

Ultrapure water 23.8ul
Promega ® Buffer D 4ul
XbaI 0.6uL
EcoRI*/PstI** 0.6uL
DNA 1ug
Final volume 40uL










We then purified the digestions using the Promega ® Wizard Sv and PCR Clean-Up system which were then eluted to 17.6 uL of ultrapure water or precipitated using Sodium Acetate and ethanol in ice.

Promega ® Buffer H 2uL
EcoRI**/PstI* 0,6uL
DNA 17,6uL
Final volume 20uL







[*] Plasmid opening [**] Fragment extraction

Run a 1% agarose electrophoresis for 55 minutes with 70V, and purify the expected weight bands using the Promega ® Wizard Sv and PCR Clean-Up system.
