From: AluMine: alignment-free method for the discovery of polymorphic Alu element insertions
A gel electrophoretic image showing the experimental validation of REF+ polymorphic Alu element insertions. Three locations from chr1:169160349, chr15:69049897 and chr3:95116523 were tested by PCR in DNA from 61 individuals. Upper bands show the presence of an Alu insertion (reference allele A), and lower bands show its absence (alternative allele B)
