This biotechnology-grade human plasma contains elevated levels of rheumatoid factor (RF ≥1000 IU/mL) and is designed for interference testing, assay validation, and control studies in immunoassay development. Rheumatoid factor is an autoantibody commonly associated with autoimmune disorders, particularly rheumatoid arthritis, and its presence can interfere with serologic and immunologic assays.

Supplied in bulk volumes ranging from 1 mL to 10 L, this material is slightly turbid and filtered through 0.22 µm membranes. It is stored at –20°C and should be aliquoted to avoid repeated freeze-thaw cycles. This reagent is ideal for laboratories developing RF-sensitive assays, validating specificity, or benchmarking RF interference across platforms such as ELISA, CLIA, and lateral flow. All plasma is sourced from human donors and processed under stringent quality controls using Type I ultrapure water (resistivity >18 MΩ·cm).

Key benefits:

  • Human plasma with RF ≥1000 IU/mL for interference and control studies
  • Bulk packaging options from 1 mL to 10 L
  • Filtered and aliquoted for reproducibility and long-term storage
  • Compatible with immunoassay platforms and serologic workflows
  • Biotechnology grade; processed with ultrapure water

Indication for Use:
This product is for Research Use Only (RUO). This product is not for administration to humans or animals. This product is not for human or veterinary diagnostic or therapeutic use.
