Figure 2From: Variation in spatial and temporal incidence of the crustacean pathogen Hematodinium perezi in environmental samples from Atlantic Coastal BaysComparison of the performance of the H. perezi qPCR assay with purified target DNA, and DNA from sediment spiked with a surrogate for the parasite. Standard curves were generated from 10-fold serial dilutions of DNA corresponding to purified cloned plasmid pES103 DNA (symbol ♦ slope of −3.39, R2 = 0.917), DNA prepared with the MoBio kit, from E. coli xcontaining plasmid pES103 (symbol ▲, slope of −2.70, R2 = 0.979), and DNA prepared from sediment spiked with E. coli containing plasmid pES103 (symbol ■, slope of −3.22, R2 = 0.993).Back to article page
