The D2050 series from Golden West BioSolutions features high-quality Rheumatoid Factor (RF) Positive Human Plasma optimized for autoimmune research, assay development, and diagnostic calibration. Each lot is screened using FDA-approved methods and confirmed non-reactive for HIV 1/2, HBV, HCV, and Syphilis. All products are preservative-free and stored at -20°C.

Three configurations are available:

• D2050-D: Defibrinated, Single Donor
