Figure 2From: DNA extract characterization process for microbial detection methods development and validationScatter plot DNA extract purity (A 260 /A 280 nm vs. A 260 /A 230 nm). Only samples with DNA concentrations greater than 17.5 ng/μL were included in the analysis. Graphs are separated by extraction method. Cell types are indicated by the data point shape, color, and rug plot color: B. cereus spores (n = 1 extracts), Red ●, S. cerevisiae (n = 9 extracts), blue ▲, B. cereus vegetative (n = 12 extracts), green ■, B. thailandensis (n = 15 extracts), purple +, and E. coli (n = 11 extracts), yellow ⊠. Dotted lines indicate the upper limits of community accepted purity ratios; light grey areas show the lower limits of community accepted purity ratiosBack to article page
