Re-gel the Scun22 PCR originally done on 2 December (but gel on 3 December was an epic saga that had no ending)
used gel cast from 3 December gel (refrigerated under cardboard since then)

no bands visible. Expecting band at about 450bp (nearly ran off, but the 506/517 band and the 396 band on ladder is visible, so should be able to see sample bands, if they were there.
