The Rheumatoid Factor Interference Blocker is a specialized reagent formulated to eliminate interference caused by rheumatoid factor (RF) in immunoassays. RF can bind nonspecifically to assay antibodies, leading to false positives and compromised data integrity—especially in assays involving human serum or plasma. This blocker neutralizes RF activity, allowing for more accurate detection of target analytes.

Composed of a proprietary blend of proteins and anti-RF antibodies, the reagent is highly concentrated and ready to use. It can be spiked directly into assay reagents at concentrations ranging from 0.02 to 2.0 mg/mL, depending on assay design. Its affinity-purified formulation ensures high purity and consistent performance across platforms such as ELISA and other antibody-based detection systems.

By minimizing background noise and enhancing signal clarity, this blocker supports reliable quantification and reproducible results in clinical and translational research.

Key benefits:

  • Neutralizes RF interference to improve assay accuracy
  • Ready-to-use liquid formulation for seamless integration
  • Effective across a wide concentration range (0.02–2.0 mg/mL)
  • Affinity purified for high specificity and purity
  • Enhances reliability of immunoassay data

Products are for in vitro research use only (RUO).
