Figure 2: Microsatellite Instability for loci D7S820. Microphotograph displaying the variant banding pattern of STR loci D7S820 in CAGB subjects. Lanes M: low base pair marker (100 bp); Lane 1: control and Lane 2-11: genomic alterations were detected by variations at the levels of absence and increased/ decreased intensity of bands that have been clearly shown in the transformed cells of various samples
