Extraction method | No. plates / samples | Time per plate | Amplification success n (%) | Observations |
---|---|---|---|---|
1. Legs directly into molecular grade water and sonicated for 10 min | 1 plate / 95 samples | 30 min | 41 (43.1%) | High sequencing failure (54 samples) |
2. Legs directly into alkaline lysis buffer and sonicated for 10 min (Hotshot) | 5 plates / 475 samples | 1hr each plate | 429 (90.3%) | Target length barcodes obtained |
3. Abdomen processed using Qiagen kit | 5 plates / 475 samples | Only 32 samples per 4hr session for DNA extraction for each plate | 306 (64.4%) | Target length barcodes obtained. Vertebrate DNA amplified |
