title: Head-to-tail primer tandem repeats generated in hemi-nested PCR.
abstract: Evidence that hemi-nested PCR protocols are prone to the development of artifacts consisting of multiple head-to-tail primer tandem repeats is presented. This phenomenon was more pronounced with the addition of a large amount of template into the second round PCR and was limited to the primer used in both first and second reactions.
