Development and characterization of nucleosomal DNA-based reference materials for the epidermal growth factor receptor gene liquid biopsy

Stable reference materials for liquid biopsy could help labs reliably detect lung cancer mutations in blood, enabling more consistent early detection.

This study developed biologically representative nucleosomal DNA reference materials for EGFR liquid biopsy standardization at low variant allele frequencies, validated across dPCR and next-gen sequencing. The materials maintained stability for 3 years, supporting reliable clinical assay validation for EGFR mutation detection.
