I wonder how the swab are processed in a very high throughput lab? is any automation system? What measures are for contamination prevention? Do need to cut the swab for DNA extraction?
The samples were incubated at 56°C for 1–3 hours, or until the tissue was completely disintegrated. The DNA was extracted from each sample using an equal amount of phenol:chloroform:isoamyl alcohol solution (25:24:1) and gently mixed for 3 minutes by inverting the tubes.
