	Try a denaturing gel. This method is usually very reliable. 

	Quick mini-PAGE (ca. 12x11x0,4 cm) with urea:
	10 g Urea
	4 ml 40% AA 19:1
	2 ml 10xTBE
	7,67 ml ddH2O
		1 hr, then + 200ul 10% APS + 20ul TEMED
	Preheat the sample in Denaturing Sample Buffer for 5' @ 95degC

	2x TBE
	90% Formamid
	0,02% Bromophenol Blue
	0,02% Xylene cyanol
