DNA Purification

DNA purification kits for genomic, plasmid, and viral DNA from diverse sample types

When you need to isolate genomic, plasmid, viral, or amplified DNA from cells, tissue, blood, plant, microbial, or environmental samples, this section covers the kits. Silica-column, magnetic-bead, and salt-precipitation chemistries each have trade-offs in yield, purity, and throughput.

Pick by sample and downstream.

1. Sample type. Cultured cells, blood, FFPE, plant, microbial, environmental, swab each have sample-specific kits that handle inhibitors.
2. Throughput. Single-column versus 96-well plate. Automated platform compatibility.
3. Output DNA size. Low-MW for cfDNA. High-MW for long-read sequencing requires column-free chemistries.
4. Purity. Column-based gives PCR-ready. Bead-based with specific buffers preferred for NGS.
5. DNA species. Total genomic, mitochondrial, viral, cell-free, formalin-degraded each have dedicated chemistry.
