Amplification facilitators and multiplex PCR: Tools to overcome PCR-inhibition in DNA-gut-content analysis of soil-living invertebrates

Polymerase chain reaction (PCR) can be used to detect prey within the gut contents of predators and allows specific trophic interactions to be studied among soil-dwelling invertebrates which cannot be examined by other approaches. PCR-inhibitory substances, however, are commonly found in DNA prepare...
