Abstract 

High levels of non-authentic sequence data can be generated by traditional PCR-based methodologies when DNA is damaged, template numbers are small and/or the target amplification size too large. We therefore present an alternate methodology based on single primer extension (SPEX) amplification; that places no pre-defined size constraints on amplification and interacts with only one of the DNA strands at the target locus.
