Ovarian Cancer Plasma
About:Ovarian Cancer Plasma is collected from consented donors with clinically confirmed ovarian cancer. Ideal for circulating tumour DNA and liquid biopsy work, CA-125 and HE4 marker research, plasma proteomics, and early-detection biomarker discovery. Available stratified by stage, histology, treatment timepoint and platinum sensitivity, with age-matched healthy controls.
About Ovarian Cancer Plasma
Ovarian Cancer Plasma for Tumour Biomarker and Liquid Biopsy Research
Ovarian Cancer Plasma is collected from IRB-consented donors clinically diagnosed with ovarian cancer and processed within one day of collection to preserve proteins, nucleic acids and metabolites. Plasma is acellular, so this product is intended for soluble-analyte and cell-free nucleic acid work rather than cell-based assays.
Ovarian Cancer Biology and Why Plasma
Ovarian cancer is a neoplastic disease. The relevant biology is tumour biology and tumour immunology, not autoimmunity.
- High-grade serous carcinoma is the most common and most lethal histological subtype, and is characterised by near-universal TP53 mutation and widespread copy number instability
- Defects in homologous recombination repair, notably germline or somatic BRCA1 and BRCA2 alterations, define the subgroup that responds to PARP inhibition
- CA-125 is the long-established circulating protein marker used to monitor disease, with HE4 studied as a complementary analyte; neither is adequate as a standalone screening test in the general population
- Late-stage presentation with peritoneal dissemination is typical, which is why early-detection biomarker research remains a major focus for this indication
- Circulating tumour DNA is shed into plasma and enables mutation detection, copy number analysis and treatment-response monitoring without repeat tissue sampling
- Plasma is the required matrix for cell-free DNA work and supports proteomic, extracellular vesicle and metabolomic discovery from the same collection
Donor Stratification 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.
