Golden West BioSolutions’ Human Plasma, Rheumatoid Factor (RF) Positive is a disease-state plasma derived from donors confirmed to have elevated RF levels, commonly associated with autoimmune conditions such as rheumatoid arthritis. This biologically sourced material is ideal for use in assay development, quality control, and diagnostic research involving autoantibodies and inflammatory markers.
The plasma is collected under stringent regulatory standards to ensure consistency, integrity, and traceability. Each lot is screened and tested to confirm RF positivity at the indicated titer threshold, and is available in various aliquot sizes for research flexibility. Our RF-positive plasma supports the development of sensitive and specific immunoassays and helps drive innovation in autoimmune diagnostics. Our most potent RF-positive plasma, with titers above 4000 IU/mL, is ideal for extreme assay tolerance testing, outlier challenge panels, and research on advanced autoimmune disease progression.
