I do PCR genotyping using the simple NaOH and Tris DNA prep, and certain recent samples only seem to be working on my more robust, virtually foolproof PCRs. To make a long story short, I believe I may have made up the NaOH to the wrong concentration (I'm about to go try to determine if it was too concentrated, or not enough). I have already added the Tris.
Is there any way of saving these samples?
EDIT TO ADD: It is *too* concentrated, by about 6.5 times.
