Microsatellite autoradiogram

    Microsatellites in the CODIS set were originally run as radioactively-labeled PCR products in a single gel electrophoresis experiment. In an autoradiogram where all loci are shades of grey, bands attributable to different microsatellite loci, but with similar molecular weights, can be difficult to distinguish. [Compare this with a fluorescently-labeled, capillary-electrophoresis profile]
