Myositis Plasma
About:Myositis Plasma is collected from consented donors with clinically confirmed idiopathic inflammatory myopathy. Ideal for myositis-specific autoantibody detection, muscle injury marker measurement, interferon-associated mediator profiling, and soluble biomarker discovery. Available stratified by clinical subtype, autoantibody status and disease activity, with matched healthy controls.
About Myositis Plasma
Myositis Plasma for Autoimmune Inflammatory Myopathy Research
Myositis Plasma is collected from IRB-consented donors clinically diagnosed with myositis and processed within one day of collection to preserve cytokines, autoantibodies, muscle-derived proteins and metabolites. Plasma is acellular, so this product is intended for soluble-analyte measurement rather than cell-based assays.
Myositis Autoimmunity and Why Plasma
The idiopathic inflammatory myopathies are autoimmune diseases of skeletal muscle, characterised by immune-mediated muscle injury, weakness and, in many patients, extramuscular involvement.
- Myositis-specific autoantibodies define clinically meaningful subgroups, and their identification is now central to classification; anti-synthetase antibodies including anti-Jo-1, anti-Mi-2, anti-MDA5 and anti-TIF1-gamma are among the best characterised
- Antibody specificity carries prognostic information: anti-MDA5 is associated with interstitial lung disease and anti-TIF1-gamma with malignancy risk, so serological subtyping genuinely changes study design
- Type I interferon signalling is prominently upregulated in dermatomyositis, and interferon-inducible soluble mediators are measurable in circulation
- Ongoing muscle fibre damage releases creatine kinase, aldolase, myoglobin and other muscle-derived proteins into plasma, providing quantitative disease activity readouts
- Immune-mediated necrotising myopathy and inclusion body myositis have distinct mechanisms from the classical dermatomyositis and polymyositis groups, so subtype is not interchangeable
- Plasma supports autoantibody immunoassays, muscle enzyme measurement, interferon signature-associated protein panels and proteomic discovery from a single acellular sample
Donor Stratification Available
- Clinical subtype: dermatomyositis, polymyositis, immune-mediated necrotising myopathy, or inclusion body myositis
- Myositis-specific autoantibody status where tested, including anti-Jo-1, anti-Mi-2 and anti-MDA5

- Creatine kinase level at collection where available
- Presence of interstitial lung disease or other extramuscular involvement
- Treatment status: treatment-naive, on corticosteroids, on conventional immunosuppression, or on IVIG
- 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.
