Evaluating the analytical sensitivity of Lacticaseibacillus paracasei 8700:2 strain-specific identification assay. Three DNA dilution series were prepared from starting concentrations of 10 ng/μl (Dilution series 1), 5 ng/μl (Dilution series 2), and 2 ng/μl (Dilution series 3). Dilution series consisted of five points each (10-fold) and each dilution was tested in triplicate to establish standard curves. The limit of detection was determined to be 0.5 pg. of DNA, corresponding to 150 target copies.
