Rheumatoid Factor Solution is a high-titer human plasma-based reagent containing ≥1500 IU/mL of rheumatoid factor (RF), a key autoantibody associated with rheumatoid arthritis and other autoimmune conditions. This solution is formulated from defibrinated human plasma and exhibits a slightly turbid appearance, reflecting its native immunoglobulin content. It is ideal for interference testing, assay validation, and immunoassay robustness studies where RF cross-reactivity or signal distortion must be evaluated.

Researchers use this solution to simulate RF-positive specimens in diagnostic workflows, assess assay specificity, and validate blocking strategies. Its high concentration and native matrix make it suitable for ELISA, nephelometry, and other immunometric platforms. All components are biotechnology grade and filtered through 0.22 μm membranes using Type I ultrapure water (resistivity >18 MΩ·cm).

Key Features:

  • High-titer RF concentration (≥1500 IU/mL) for interference modeling
  • Human plasma matrix ensures physiological relevance
  • Validated for immunoassay robustness and specificity testing
  • Biotechnology grade with 0.22 μm filtration for purity and consistency
  • RUO designation: not for clinical or therapeutic applications

Indication for Use:
This product is for Research Use Only. It is not intended for human or animal use, diagnostic procedures, or therapeutic applications.
