MinION
MinION is part of the Nanopore Wiki learning path. MinION is a portable nanopore sequencing device associated with Oxford Nanopore Technologies and widely used for field, teaching, and laboratory sequencing.
Core concepts
- MinION uses disposable flow cells with many nanopore channels.
- It supports real-time sequencing and portable workflows.
- Run success depends on sample quality, library preparation, flow cell state, and software configuration.
- Downstream interpretation requires appropriate bioinformatics and quality control.
Scientific basis
- MinION uses disposable flow cells with many nanopore channels.
- It supports real-time sequencing and portable workflows.
- Interpretations should be tied to measurable quantities, experimental controls, and documented analysis settings.
- Claims should distinguish direct observations from downstream inference.
Practical workflow
| Step | Description |
|---|---|
| 1 | Check flow cell status and plan library input. |
| 2 | Prepare and load the sequencing library. |
| 3 | Monitor run metrics such as active pores, yield, read length, and quality. |
| 4 | Analyze reads with a documented pipeline. |
Typical applications
- Rapid microbial and viral sequencing.
- Teaching long-read sequencing concepts.
- Field and resource-limited deployments.
- Small genome assembly and targeted sequencing.
Quality checks
- Record platform, pore or flow-cell type, chemistry, voltage or acquisition settings, and software versions.
- Use negative controls, positive controls, and replicate measurements where the claim depends on specificity.
- Report limitations such as noise, bias, sample degradation, pore instability, or model-dependent analysis.
- Do not treat vendor specifications as a substitute for application-specific validation.
Interpretation limits
- Assuming portability removes the need for sample quality control.
- Using old basecaller models without recording versions.
- A single result should not be generalized beyond the sample, protocol, instrument state, and analysis pipeline used.
- Medical, legal, regulatory, or commercial decisions require domain-specific validation beyond this educational summary.
