Description
Color-dyed microspheres are latex microspheres obtained through staining, where the dyes are embedded inside the microspheres and do not leach into the surrounding water or buffer solution. The surface properties of the microspheres remain unchanged, preserving the characteristics of latex microspheres. To meet the demands of lateral flow immunoassays and address the limitations of colloidal gold, our company has developed a variety of color-dyed microspheres with different colors and sizes for selection.Product Features:- Bright and vibrant colors, higher sensitivity compared to colloidal gold.
- Requires less antibody usage, cost-effective.
- Low inter-lot variation, suitable for large-scale production.
- Adjustable functional groups and content to meet various product labeling needs.
Technical Specifications:- Material: Polystyrene and dyes.
- Particle Sizes: 200nm, 300nm, 400nm.
- Uniformity: CV<5%.
- Surface Functional Groups: Carboxyl (COOH).
- Dispersant: Pure water.
- Additives: Trace amounts of surfactants.
- Storage Conditions: Store at 4-25°C, strictly avoid freezing
