24317821-6	1981	Lesions were also detected by staining solvent-extracted and proteinase digested leaves with ethidium bromide.	Ethidium	93-109	endogenous retrovirus group K member 25	Homo sapiens	61-71	
2042745-5	1991	(iii) A proteinase that digests histones will make more DNA available for ethidium bromide intercalation, thereby producing an increase of fluorescence.	Ethidium	74-90	endogenous retrovirus group K member 25	Homo sapiens	8-18	
2042745-6	1991	Proteinase activity can easily be determined, in the presence of a DNA/histone complex, from the rate of ethidium fluorescence increase.	Ethidium	105-113	endogenous retrovirus group K member 25	Homo sapiens	0-10
