library with different sizes
I wish to use MinION to sequence 11 PCR products. Most of them are ~ 2 or 3 kb. Another two are 4kb and 9kb respectively. Is it possible to add the adapter and run them together, although they have different sizes? Thank you very much.

In theory ONT 2D libraries should not be as sensitive to size variations as illumina/454 amplicon sequences used to be, so it should be possible to have a variety of amplicon sizes.
But make sure you use an excess (something like 2-4X) of MOLAR concentration of the larger fragments compared to the small ones, to compensate for lower ligation and loading efficiencies.
And I would still rather avoid mixing anything under 2kb with larger fragments.
The exact size correction coefficients/functions would have to be worked out empirically. -
You may have to adjust the molar input ratio with the adapter sequences, the protocol contains a note about having smaller fragments.
But mixing shouldn't be a problem.Comment

NGS has revolutionized clinical microbiology by offering new ways to identify and surveil pathogens without prior knowledge of the target. One popular approach is 16S rRNA and ITS amplicon sequencing, which targets specific microbial markers. But studies are increasingly incorporating shotgun metagenomics, a technique that sequences all DNA from a sample without targeting specific microbial markers. This approach allows more detailed taxonomic classification, detection...Yesterday, 06:46 AM -
Tumors contain complex mixtures of cell populations that evolve in response to treatment and host-specific factors. Tissue biopsies provide only static snapshots of a tumor’s state. But what if we could follow that evolution over time using a minimally invasive technique?
Liquid biopsies can detect tumor-derived material circulating in the bloodstream, providing a way to study treatment response, detect emerging resistance, and discover new biomarkers. Circulating...10-14-2026, 09:55 AM
