thanks! i will try 1:1

You may try NVIGEN MagVigen. It's observed that AmPure XP lags MagVigen in primer dimer/adapter dimer cleanup. You can check these different contamination levels (>200%, >100%, >50%, 20%) (https://www.nvigen.com/dna-clean-up/)Originally posted by yuehuang View PostThanks much for the tips. I was always bothered by the primer dimer when used NEB kits for library prep. The AMPure XP worked fabulously for size selection, however didn't work for getting rid of the primer dimer. I had to use Pippin Prep to clean-up the products, which caused more than half loss. After switched to Nextera kit, no more primer dimer problem, but primer contamination presented sometimes. The manufacturer's suggestion is only 25uL beads for 50uL products. I would try your 1.8:1 ratio next time.
Disclosure: I work at NVIGEN. We cordially invite you to try MagVigen. In case you find problems using it, we will be happily work with you to troubleshoot or fine tune it to meet your needs.Comment

There is a charter picture here, which demonstrates beads volume vs sample volume (note: not sample to beads). NVIGEN MagVigen uses the same protocols as AmPure XP.Originally posted by XIAOXIAO View Post

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...Yesterday, 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...
