Cost-Effective Strategies for Pacbio Sequencing
Pacbio sequencing offers powerful insights into genomic structures, but it can be costly. Let’s explore strategies to maximize sequencing efficiency and reduce expenses.
Optimizing Sample Size and Quality
High-quality DNA samples are crucial for cost-effective Pacbio sequencing. The Revio system needs at least 3 μg of high-quality, high molecular weight DNA for whole genome sequencing, while the Sequel II can work with as little as 5 ng of DNA18. Ensure your samples meet these standards to avoid costly repeats.
Multiplexing is a smart way to boost sequencing efficiency. HiFi sequencing allows for 10 bp indexes during DNA library construction, using one of 384 SMRTbell adapter indexes19. This approach can significantly cut per-sample costs.
Collaborations with Research Institutions
Research collaborations can open doors to more affordable Pacbio sequencing. Many core facilities offer competitive rates. For example, one top Pacbio partner facility charges about $2,045 for Revio library prep and sequencing, with an expected output of 90 Gb18. This is far more cost-effective than using three Sequel II SMRT cells to achieve the same output, which would cost around $8,686.5018.
Consider these options for cost-effective sequencing:
| Strategy | Benefits | Considerations |
|---|---|---|
| Multiplexing | Lower per-sample costs | Requires careful sample prep |
| Core facility collaboration | Access to latest tech at lower rates | May have wait times |
| Optimized sample quality | Reduces need for repeats | May require extra prep time |
By focusing on these strategies, you can harness the power of Pacbio sequencing while keeping costs in check. Remember, the key lies in careful planning and smart collaborations.
