Figure 3: Microsatellite Instability for loci D13S317. Microphotograph displaying the variant banding pattern of STR loci D13S317 in CAGB subjects. Lanes M: low base pair marker (100 bp); Lane 1: control and Lane 2-6: 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.
