An approach was developed to recover prey DNA from gut contents of nauplii of a predatory copepod by blocking the detection of predator, Tortanus dextrilobatus, with ligase and a blocking oligonucleotide and amplifying prey DNA with universal primers. Adding 25 U of ligase improved predator clamping, while 100 and 200 U reduced efficiency. Field collected nauplii consumed a broad range of prey.This dataset measures the performance of the blocking oligonucleotide with increasing amounts of ligase and at two ratios of prey to predator DNA concentration. Data are also shown for wild nauplii at 25 and 100 U of ligase.
This dataset is published in Figure 2, Craig et al (2014).
