Run a minigel to check the digest. Use a preparative comb, or several wells of a standard comb. We have found that this step, for which many people have reported large DNA losses, may not be necessary - unless your sample is contaminated with glass beads. Use your best judgement. You might try Elutip on only half your sample if you are worried about DNA loss.
Ethanol precipitate the DNA solution.
The importance of the washing and drying steps cannot be overemphasized, as both residual salt and ethanol are lethal to a developing embryo. This protocol works well for us. If you choose to use an alternative method please provide us the protocol when you submit your sample. The DNA should be as clean as possible, free of salt and other contaminants that could result in decreased embryo survival, and prepared using a method that will not shear the fragment.
