qPCR detection of type-specific neurotoxin DNA. Each toxin type DNA amplified with type-specific primers and probes. Assay sensitivity is shown in the table. Each toxin type DNA was amplified with its cognate primer and probe set. The DNA was diluted based on its concentration and genomic size such that each reaction contained a known number of DNA target gene copies. Dilutions ran from 105 genomic copies to 1 genomic copy. Each dilution series was run with six replicates to determine reproducibility. Plasmid standards were amplified along with each dilution series to determine exact copy number in each reaction. Results represent the percentage of the six replicates that contained accurate copy numbers in each reaction.
