Surfactant S17

Surfactant S17(ON-870) is a low foam emulsifier and also a good wetting agent, dispersant and detergent. It belongs to non-ionic surfactants and has excellent chemical stability and biocompatibility. It can form stable micelle structures in aqueous solutions, effectively reducing the surface tension of the solution.surfactantS17The colloidal gold urine product has better effects, such as improving matrix effects, increasing sensitivity, and reducing non-specific effects.

Characteristics: Low foaming, strong wetting, dispersibility, washability, suitable for colloidal gold immunochromatographic systems (especially urine samples).

Surfactant S17The mechanism of action:

Improving matrix effect: Regulating the viscosity and surface tension of urine samples through hydrophilic hydrophobic balance, reducing interference from non target substances such as salts and metabolites.

Enhance sensitivity: Promote efficient binding between colloidal gold labeled antibodies and target antigens, reducing signal loss caused by particle aggregation.

Reduce background color: Inhibit non-specific adsorption of colloidal gold (such as nitrocellulose membrane or impurities in the sample), optimize signal-to-noise ratio.

Stable colloidal gold: By binding hydrophobic chains to the surface of colloidal gold, hydrophilic chains form steric hindrance to prevent particle aggregation.

The recommended final concentration is 0.01% -0.2% (gradient optimization is required).
