ppmSeq sounds interesting, anything out there already about it?

But what if you don't have the tumor? DOESN'T MATTER. ppmSeq is so error robust that you don't need tumor sequencing to detect ctDNA. Hello, new era of tumor-naive patient monitoring.

Application 1: tumor-informed ctDNA detection. ppmSeq is perfectly suited for this. We sequence the tumor, and mine for mutations in the blood with ppmSeq. This enabled part per TEN MILLION ctDNA detection. PAR PER 10M. Insanity.

Initial benchmarking shows massive scalability of ppmSeq, ~40-60% of our reads encode dsDNA molecules. The more you sequence, the more get dsDNA
CRAZY STAT: ppmSeq is a PCR-FREE method that works with ONE NANOGRAM of input. ONE!!!

Highly accurate sequencing OR high throughput? We refuse to choose.

Introducing ppmSeq, a method built to deliver both. Our latest from the @landau.bsky.social lab with Ultima Genomics
