Fig. 2From: Alu SINE analyses of 3,000-year-old human skeletal remains: a pilot studyThe photo shows seven successfully amplified amplicons of an internal Alu primer-based amplification. The expected fragment lengths vary from 118-194Â bp. The marks on the base pair ladder are situated at 150Â bp and 350Â bp. For these seven Alu loci, the presence band for DO 3750 was proved via internal Alu amplification. The asterisks indicate reverse Alu inserts. In these cases, the primer pairings are an internal Alu primer with the reverse Alu flanking primer, whereas the samples without asterisk were amplified with an internal Alu primer and the forward Alu flanking primerBack to article page
