Sensitive and Reliable Results

Concentrations of ctDNA vary among tumor types and among individuals. This variability in ctDNA concentration creates the need for a highly sensitive technology to detect genomic mutations at lower concentrations. The Follow It assay detects mutations down to 0.1% variant allele frequency*.

Follow It detects common, clinically relevant genomic alterations in solid tumor samples, including single-base substitutions (SNVs), small deletions, and insertions (up to 24bp). It evaluates the mutation status of tumor DNA at 337 hotspots and 26 exons in 38 known cancer-associated genes simultaneously.

Follow It targets genes for non-small cell lung cancer, melanoma, colorectal cancer, GIST, basal cell, breast cancer, endometrial, and other solid tumor cancers.
