Our lab has built a drop-seq setup. Going over the protocol, I see that the cells are lysed in a solution of sarkosyl, Ficoll-400, tris, EDTA, and DTT. I'm not intimately familiar with the biochemstry of this lysis buffer. I'm wondering if it is effective at inactivating endogenous RNAses? I haven't found anyone online that has discussed degradation of RNA at this stage. But the pumping can take quite a while, depending on the scale of the experiment (at least 15 minutes per sample). I am just curious if this is something I should or shouldn't be concerned about.

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...
