Automated nucleic acid extraction is supposed to make lab life simpler: you automate the workflow, throughput goes up, errors go down and the researcher who used to spend three hours pipetting can now spend that time thinking instead.
Where nucleic acid automation breaks down
An automated high-throughput workflow may perform well for the sample type it was originally configured to process. Then the project pivots. Or a collaboration brings in a different matrix, and now the lab also needs to do plant genomics alongside microbiome work, or move from blood to tissue.
Yes, processing hundreds of samples efficiently is impressive. Processing blood samples, then moving to stool or tissue on the same platform without rebuilding your automated workflow each time, is something else entirely. But the point is, automation and flexible chemistry should be designed together.
How sample type and target shape extraction chemistry
Tissue, blood, stool and plant material all bring different biochemical conditions into a nucleic acid extraction workflow.
Tissue may contain high levels of protein, lipids or nucleases, depending on its source. Stool brings microbial complexity and amplification inhibitors. Plant material may contain polysaccharides, polyphenols and other compounds that interfere with PCR and NGS if the lysis and cleanup chemistry are not designed to remove them.
A one-size-fits-all lysis approach may work for straightforward samples, but difficult matrices tend to expose its limitations. The pretreatment step matters. The inhibitor removal step matters. Whether your lysis happens on board the instrument or requires a manual step upstream matters, especially in pathogen workflows, where biosafety considerations mean every extra manual touchpoint carries operational risk.
And sample type is only one layer. Your purification target matters too. Genomic DNA, total RNA, microRNA, viral nucleic acids or plasmid DNA each demands a different purification chemistry.
Chemistry needed to isolate these targets already exists. The gap is whether automated nucleic acid purification instruments can switch chemistries seamlessly without a workflow rebuild every time the science changes direction.
What flexible automation looks like
QIAsprint Connect approaches this challenge through a modular kit system. Each workflow is assembled using three types of components, each with a defined role:
- The PrepSet addresses the conditions introduced by the starting material
- The Essential Kit provides the automated purification backbone
- Optional add-on modules are available when further processing is needed.
The current QIAsprint applications cover starting materials including whole blood, tissues and cells, plant material, stool, pathogens and plasmid DNA on a single instrument, with more applications planned in the future. This way, laboratories can select components suited to their sample type and purification target while maintaining a consistent automated process.
That is what it takes to get past nucleic acid automation’s final boss. It’s simply not just a faster instrument. It’s a system where automation and application-specific chemistry work together seamlessly, and that’s the version of automation we built.
