Two-color electropherograms of D9S171 loci amplicons showing complete loss of heterozygosity (sample set 22). (A,B) Normal sample amplified with the ET-R110 (blue) labeled primer and the tumor sample amplified with the ET-ROX (red) labeled primer, respectively. (C) Co-injected mixed sample. The arrows indicate the two alleles being compared. The slight difference in intensity is caused by dilution of one sample into another.
