I have around 10% adapter dimers, relative to the molarity of my target product, in my final library. I am trying to avoid another cleanup to reduce costs. What are the maximum amount of adapter dimers you have run with? Should I expect to lose about 10% of my reads?

I wouldn't sequence libraries that were much more than 2 or 3% dimer.
Also, keep in mind that the dimers will cluster much more efficiently than your library so you will lose closer to 20 to 30% of your reads.
So I guess you have to decide if you want to spend a little extra money on another cleanup or spend money sequencing dimers.Josh Kinman -
Thanks for the advice. Have you sequenced with that much? I have seen that recommendation on the boards, but wondering if I could get away with more.
This would be for more than a single experiment or I would happily do another cleanup.Comment

You may lose (significantly) more than 10% data. Short fragments preferentially cluster over longer ones and your adapter dimers would fall in the first category.Last edited by GenoMax; 12-17-2015, 11:32 AM.Comment

For future samples you could also try diluting your adapters. This would reduce the amount of dimers in your final library and could save you from needing to perform an additional cleanup.Josh KinmanComment

You can get away with more, but you will be losing a significant amount of reads to the dimers. More often than not the cost per reads lost will be more than what the beads would cost.Originally posted by Ingeneious View Post
If you are multiplexing samples you can also perform a cleanup after pooling which could save you some on beads.Josh KinmanComment

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 -
Researchers using sequencing and genomics tools often have to make trade-offs. They can choose between speed or scale, short reads or long-range information, or targeted panels or a view of the whole transcriptome. New technologies that have been released this year are built to address those tough choices.
We asked six companies the same four questions to learn about their latest products. The new technologies bring a lot to the table, including rethinking sequencing...
