Fig 1. Single and mixed animal DNA samples for the fluorescence interference test.

Fig 1

Single samples contained beef or pork DNA. Mixed samples included Mix1 (100 ng beef and 100 ng pork DNA), Mix2 (100 ng beef, 100 ng pork, and 100 ng chicken DNA), and Mix3 (100 ng beef, 100 ng pork, 100 ng chicken, and 100 ng mutton DNA). Three replicates per sample were analyzed by dddPCR. The values are expressed as mean ± SEM. Each value represents the average of three experiments. Error bars represent the standard deviation between the three replicates. ns: non-significant difference compared to the single group.
