COVID diagnostics from @DNAnudge

By | September 21st, 2020|Categories: Diagnostics Tech, Methods and applications|0 Comments

A recent paper in The Lancet Microbe reports the first data from CovidNudge: DnaNudge’s rapid, lab-free COVID-19 test. The test: DnaNudge uses a SNP-genotyping technology developed by The Technology Partnership in Cambridge and explained in US10093965B2 patent. A sample is introduced into the Nudge cartridge, a disposable, sealed, and integrated lab-on-chip device,  […]

Brain cancer testing without the invasive biopsy from @decarvalho_lab

By | June 23rd, 2020|Categories: Diagnostics Tech, Early detection, Epigenomics|0 Comments

Brain cancer is difficult to diagnose and stratify without an invasive biopsy. Daniel De Carvalho’s group have used their cfChIP-Seq technology to non-invasively diagnose and classify brain tumours, potentially removing the need for surgical tissue biopsies. The power of the assay comes from its use of […]

Tumour-informed sequencing to increase the sensitivity of ctDNA liquid biopsy

By | June 18th, 2020|Categories: ctDNA, Diagnostics Tech, MRD|0 Comments

A new paper from Nitzan Rosenfeld’s group at CRUK-CI (my old stomping ground) reports astounding sensitivity for ctDNA liquid biopsy. In “ctDNA monitoring using patient-specific sequencing and integration of variant reads” Jonathan Wan and his co-authors performed whole exome sequencing on tumour biopsies (and PBMCs) […]

Avida Biomed: early cancer detection with methylation

By | June 5th, 2020|Categories: Diagnostics Tech, Early detection, Epigenomics, MRD|0 Comments

Avida Biomed are an early startup who have developed a novel targeted methylation sequencing technology: Point-n-Seq, for cancer early-detection. Point-n-Seq uses targeted methylation sequencing, which performs enrichment of target molecules directly from cfDNA before bisulfite conversion and amplification. Target panels are small 1-1000 markers. The […]

Evidence for the use of cfDNA Fragmentome for early detection and monitoring of cacner

By | November 27th, 2019|Categories: Diagnostics Tech, Methods and applications, Next-generation sequencing|0 Comments

In Inference of transcription factor binding from cell-free DNA enables tumor subtype prediction and early detection researchers at the Institute of Human Genetics in Austria demonstrate the use of cfDNA for cancer detection and monitoring. The group performed deep ATAC-Seq and deep cfDNA nucleosome mapping to […]
