Analysis of yesterday DNA digestion

The digested DNA of yesterday was analysed once more time by electrophoresis on a 0.8% agarose gel (about 30 minutes at 100 W). The ladder used was the 1 kb DNA ladder (New England Biolabs). 5 µL of each sample with 1 µL of loading dye were loaded.

D129	B0030	2	SpeI	PstI	BV	2080 pb				8 & 9

Results : Each of the samples was succesfully digested and purified except for the sample D108. It seems that the QIAprep columms (from the QIAGEN Minipreps kit) can be used instead of the QIAquick columms (for DNA Gel Extraction).
