Colorectal Cancer Plasma
About:Colorectal Cancer Plasma from consented donors diagnosed with colorectal cancer, covering both colon and rectal primaries. Suitable for liquid biopsy development, circulating tumour DNA (ctDNA) analysis, cell-free DNA methylation work, and profiling of CEA and immune-related biomarkers. Stratified by stage, mutation and MMR status.
About Colorectal Cancer Plasma
Colorectal Cancer Plasma for Liquid Biopsy and Tumour Immunology Research
Colorectal Cancer Plasma is collected from IRB-consented donors clinically diagnosed with colorectal cancer and processed within one day of collection to preserve circulating tumour DNA, extracellular vesicles, proteins, cytokines and metabolites. Colorectal cancer is a neoplastic disease that develops through progressive accumulation of somatic alterations — classically involving APC, KRAS, TP53 and mismatch repair genes — with tumour-immune interactions shaping progression and response to therapy. Plasma is acellular and is the standard matrix for liquid biopsy and soluble-analyte work.
Tumour Biology and Why Plasma
- Circulating tumour DNA (ctDNA) enables non-invasive detection of somatic alterations including KRAS, NRAS, BRAF V600E and PIK3CA, and detection of resistance mutations emerging on anti-EGFR therapy.
- Plasma rather than serum for cell-free DNA: serum carries far more background leukocyte-derived genomic DNA generated during clotting, which dilutes the tumour fraction.
- Minimal residual disease and recurrence monitoring after surgery is one of the most active applications of ctDNA in colorectal cancer, and benefits from serial collections.
- Methylation markers such as methylated SEPT9 and related cell-free DNA methylation signatures underpin non-invasive screening research.
- Protein tumour markers including CEA and CA 19-9 support marker validation and combined protein-plus-ctDNA panel development.
- Tumour immunology: microsatellite instability-high and mismatch repair-deficient tumours are immunotherapy-responsive; soluble checkpoint molecules, cytokines and chemokines support immune evasion and response research.
Donor Stratification Available
- Primary tumour site: colon versus rectum, and right- versus left-sided colon where documented
- Stage at collection, including localised versus metastatic disease
- Mutation status where available: KRAS, NRAS, BRAF

- Hereditary syndrome context where documented, including Lynch syndrome or familial adenomatous polyposis
- Longitudinal or serial collections from the same donor, on request
- Matched healthy controls available

Where can I find your complete catalog?
You can find our full product catalog here.
How long can samples be stored?
Storage depends on sample type but often cryopreserved samples stored in liquid nitrogen can be stored for years.
What customization options are available?
Extensive customization is available. To discuss your project request a quote or email us at learnmore@sanguinebio.com.
Do you offer prospective collections?
Sanguine offers flexible prospective collection services tailored to fit your research. For more information and to request a quote, please see: our prospective biospecimen collection services page.
What is the turnaround time for custom collections?
Timelines depend on condition, sample type, and I/E criteria but we often start collection within 2 weeks of signed agreement.
Do you have samples in stock?
YES - we have in-stock inventory. You can also email us at learnmore@sanguinebio.com as we continually get new samples in our inventory.
What does unique donor mean?
Each sample from a different individual - Unique donor means each sample comes from a different person, ensuring biological diversity in your study.
Are samples collected under IRB-approved protocols?
YES - "IRB-approved collection protocols" and IRB approval documentation available upon request. Sanguine utilizes two internationally-recognized IRBs (Advarra and WCG IRB) for review and approval.
