Rheumatoid Arthritis Bulk Plasma
About:Rheumatoid Arthritis Bulk Plasma is collected by apheresis from IRB-consented RA donors using Acid-Citrate-Dextrose Formula A (ACDA) and tested negative for HIV, HBV, and HCV. High-volume single-donor material for rheumatoid factor and anti-CCP assay development, positive control and reference matrix use, autoantibody purification, and large-scale proteomic work.
About Rheumatoid Arthritis Bulk Plasma
Rheumatoid Arthritis Bulk Plasma for Autoimmune Assay Development and Biomarker Research
Rheumatoid Arthritis Bulk Plasma is collected from IRB-consented donors diagnosed with rheumatoid arthritis (RA) using apheresis, with ACDA (Acid-Citrate-Dextrose Formula A) as the anticoagulant. High-volume, single-donor collections are tested and confirmed negative for HIV, HBV, and HCV, and are available fresh with custom volumes on request. Research Use Only (RUO).
Disease Serology and Why Bulk Plasma
- Rheumatoid arthritis is a systemic autoimmune disease centred on inflammation of the synovial membrane, with synovial hyperplasia, pannus formation, and progressive cartilage and bone erosion.
- Two autoantibody systems define the serology: rheumatoid factor, directed against the Fc region of IgG, and anti-citrullinated protein antibodies, commonly measured as anti-CCP. ACPA are highly specific for RA and can be detectable years before symptom onset.
- Seropositive and seronegative RA behave as partly distinct entities, and the strongest genetic association, the HLA-DRB1 shared epitope, is largely confined to ACPA-positive disease.
- TNF and IL-6 are validated therapeutic targets in RA, and acute-phase reactants such as C-reactive protein track systemic inflammatory activity, so plasma carries directly interpretable disease-relevant analytes.
- High-volume single-donor plasma is what makes autoantibody-rich material practical to use at scale: as a positive control and reference matrix for RF and anti-CCP assay development, for antibody enrichment and purification, and for large multiplex or proteomic panels that would exhaust a standard draw.
- Plasma is acellular. This product is for soluble analyte, autoantibody, and proteomic work, not for flow cytometry or any cell-based assay.

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.
