Circulating tumor cells (CTCs) and cell-free DNA (cfDNA) Analysis

Analyze circulating tumor cells and genomic material in blood as a non-invasive approach to study tumor biology Contact us

Liquid biopsy, including analysis of CTCs and cell free DNA in blood, can provide a more easily accessible way to obtain information of processes in other areas of the body, compared to tissue biopsies.

These liquid biopsy products can serve as potential biomarkers for indications of status, origin, progression and treatment response. However, found in low concentrations, with rare mutations, or in a fragmented condition, you need reliable tools that give you confidence in the signal you detect, followed by the appropriate downstream platform for analysis.

Precision specializes in developing approaches and technologies to maximize the biomarker information available from limited liquid biopsy samples.


Gain molecular insights from your liquid biopsy products

Leverage a suite of platform technologies into optimized workflows for detailed analysis of CTCs and cell-free nucleic acids which result in high specificity, superior recovery rates, and enhanced purity, so you can focus on your clinical end points. 

  • circulating-tumor-cells


    Analyze CTCs to gain information about the underlying status of the cancer:

    • Multiple DNA abnormalities
    • CTC numbers
    • RNA expression and fusion transcripts
    • Protein expression
    • In vitro/in vivo culture
  • auto-dna-purification


    Elevated in certain disease process like inflammatory conditions and cancers, cfDNA genomic sequences can provide insight on cancer type by revealing:

    • Amplification and deletions
    • Translocations
    • Point mutations
    • Chromosomal abnormalities
    • Number of mutant molecules

Analyze with a full suite of downstream assays

Precision's optimized workflows allow for the most relevant enriched populations to be further characterized. Our multi-platform approach supports complex development programs, including immuno-oncology, autoimmune, and neurology therapeutic development.
  • Targeted NGS

    Targeted NGS for genomic profiling

    Enable comprehensive genomics profiling with cancer-specific panels capable of detecting key immuno-oncology gene signatures (TMB, MSI) plus all main variant classes.
  • Gene expression

    Gene expression

    Gene expression with ddPCR

    Detect and discover biomarkers with high analytical specificity and sensitivity using ddPCR technology.
  • Single-cell

Frequently Asked Questions

How do CTCs form?

As a tumor grows, cancer cells along the edges of the tumor migrate into the bloodstream and circulate through both the blood and lymphatic system as CTCs (also known as metastasis). These CTCs, present in approximately 1-100 cells in 5 million RBCs, can continue in circulation, join with other circulating tumor cells, or become lodged in outlying tissues to form additional tumors. When captured and concentrated, these CTCs can then be analyzed, providing information about the underlying status of a disease. Significantly, this liquid biopsy process is much less invasive to the patient than a traditional surgical biopsy.
