Colorectal Cancer Serum
Colorectal Cancer Serum from IRB-consented donors with confirmed colorectal cancer, processed and frozen within 24 hours of collection. Supports CEA and CA 19-9 tumour marker assay work, systemic inflammatory and cytokine profiling, tumour immunology research across MSI-high and MMR-proficient disease, and serum proteomics. Donors can be stratified by stage, tumour sidedness, MSI/MMR and RAS/BRAF status, and treatment, with matched healthy controls available.
Colorectal Cancer Serum for Tumour Immunology and Oncology Biomarker Research
Our Colorectal Cancer Serum is sourced from IRB-consented donors clinically diagnosed with colorectal cancer. Each sample is processed and frozen within 24 hours of collection to ensure consistency and high quality for oncology biomarker, tumour immunology and translational research. Colorectal cancer is a neoplastic disease that develops through progressive somatic genetic change in colonic epithelium rather than through immune self-recognition.
Why Serum for Colorectal Cancer Research
- Carcinoembryonic antigen (CEA) is the best-established circulating marker in colorectal cancer and is measured in serum. It is used for post-resection surveillance and treatment monitoring rather than for screening, and disease-state serum is essential for developing or benchmarking CEA and CA 19-9 assays.
- Most colorectal cancers follow the adenoma-carcinoma sequence with sequential APC/WNT, KRAS and TP53 alteration. A distinct subset is mismatch repair deficient and microsatellite instability high; these tumours are heavily lymphocyte-infiltrated and respond to immune checkpoint blockade, so dMMR/MSI-H versus proficient tumours give very different soluble immune profiles.
- RAS and BRAF mutation status determines eligibility for anti-EGFR antibody therapy, and matched serum from genotyped donors supports work on circulating correlates of targeted-therapy response.
- Serum captures the systemic inflammatory host response to tumour burden, including CRP, IL-6 and neutrophil-related indices that carry prognostic weight in colorectal cancer independent of stage.
- Serum is the matrix on which most commercial tumour marker and autoantibody-panel immunoassays are validated, making it the practical choice for head-to-head assay comparison work.
- For circulating tumour DNA and methylation-based approaches, plasma is generally the preferred matrix; matched colorectal cancer plasma from the same donors can be requested alongside serum.
