Abnova provides an ISO15189 medical laboratory service to physicians and clinical researchers investigating circulating tumor DNA (ctDNA) released into the peripheral blood from tumor mass of cancer patients. Our capability is supported by a streamlined platform for ctDNA extraction, purification, library preparation and next-generation sequencing. ctDNA liquid biopsy is a precision tool for identifying and tracking cancer transformation and metastasis. It has significant clinical impact in cancer diagnosis, prognosis, treatment, and monitoring in the new era of personalized medicine.

Flowchart

 
 

Specimen Requirement
  • Human whole blood: collect at least 4ml whole blood in EDTA tube (purple cap) at room temperature.
  • Sample shipment: keep whole blood sample in room temperature after blood collection and throughout transportation.
  • DNA preparation: extract genomic DNA from the plasma fraction of the whole blood sample on the same day of collection and store at 4°C.
 
 

Whole Blood Fractionation, Genomic DNA Extraction, Library Preparation, Next-Generation Sequencing, and Gene Mutation Analysis
  • Whole blood fractionation: centrifuge and separate the whole blood into plasma, buffy coat (white blood cells & platelets), and erythrocyte fractions.
  • DNA extraction: extract genomic DNA from the plasma fraction followed by DNA purification and quantification.
  • Library preparation: fragment and size the genomic DNA, convert to double-stranded DNA, attach oligonucleotide adaptors, and quantitate library product.
  • Next-generation sequencing: perform hotspot and exon sequencing of mutated genes of interest.
  • Gene mutation analysis: annotate and compare cancer gene mutations including variants with published literature and public databases.
 
 

Analytical Methods
