Rhodasurf ON870Chemical Name: Ethoxylated Oleyl Alcohol
Category: Non-ionic surfactant
Characteristics: Low foaming, strong wetting, dispersing, and cleaning properties. Suitable for colloidal gold immunochromatographic systems (especially for urine samples).
Mechanism of Action
•Mitigates Matrix Effects: Regulates the viscosity and surface tension of urine samples through hydrophilic-lipophilic balance, reducing interference from non-target substances (e.g., salts, metabolites).
•Enhances Sensitivity: Promotes efficient binding between colloidal gold-labeled antibodies and target antigens, reducing signal loss caused by particle aggregation.
•Reduces Background Staining: Suppresses non-specific adsorption of colloidal gold (e.g., to nitrocellulose membranes or impurities in samples), optimizing the signal-to-noise ratio.
•Stabilizes Colloidal Gold: The hydrophobic chains bind to the surface of colloidal gold, while the hydrophilic chains form a steric hindrance layer to prevent particle aggregation.
