From: Optimized DNA-based identification of Toxocara spp. eggs in soil and sand samples
DNA extraction efficiency on serial dilutions of Toxocara canis eggs spiked in 10-g sand and 10-g soil samples. This figure shows standard curves expressing Cq values from sand and soil samples spiked with tenfold serial dilutions (104 to 1) of T. canis eggs. DNA extraction was performed using the DNeasy® Power Max® Soil Kit. DNA from sand samples was used unpurified and undiluted, whereas DNA from soil samples was purified and diluted 1:10
