FFPE Tumor Tissue DNA Service

Formalin fixed, paraffin embedded (FFPE) tumor tissue DNA analysis by NGS for personalized cancer management.

Abnova Diagnostics provides ISO15189 medical laboratory service to physicians and clinical researchers requiring formalin fixed, paraffin embedded (FFPE) tumor tissue DNA molecular characterization. Our capability is supported by a fully automated platform for FFPE tissue DNA extraction, multiplex PCR-based targeted enrichment, library preparation, next-generation sequencing, and gene mutation analysis. This robust workflow increases traceability and reproducibility, and improves quality and efficacy of cancer mutation studies. Targeted sequencing of actionable mutations have important implications in cancer diagnosis, prognosis, treatment, and monitoring in the new era of personalized medicine.

Specimen Requirement


  • Human tissue sections: 3 unstained, positively charged sequential sections from 10% formalin fixed, paraffin embedded (FFPE) tissue block. Preferred tissue fixation is 6-48hours. Recommended tissue section thickness is 4-5 microns. Tissue sections must be assayed within 6 weeks of preparation.
  • Shipment: tissue sections are kept at room temperature throughout transportation.


DNA Extraction, Library Preparation, Next-Generation Sequencing, and Gene Mutation Analysis


  • DNA extraction: extract the genomic DNA from FFPE tissue followed by DNA purification and quantification.
  • Library preparation: fragment and size the genomic DNA, enrich multiple PCR-based targets, pool amplicons, and prepare library.
  • Next-generation sequencing: perform targeted sequencing of cancer mutations based on preselected gene panel.
  • Gene mutation analysis: annotate and compare cancer gene mutations including variants with published literatures and public databases.


Analytical Methods


  • Next Generation Sequencing (NGS)
