Latex Particles
A high-performance portfolio of monodisperse polystyrene latex particles (latex beads) engineered specifically for hemostasis turbidimetric assays, latex agglutination tests (PETIA), and rapid diagnostic platform development. Sourced through high-precision emulsion polymerization, these beads deliver outstanding batch-to-batch reproducibility, precise size uniformity, and extensive shelf stability.
Applications & Uses:
- Raw materials for latex agglutination and immunoturbidimetric (PETIA) reagents
- Sensitization of lateral flow diagnostic test strips
- Particle-enhanced immunoassay system development
- Standard reference particles for size calibration and microfluidic research

Benefits:
- Precise size control: Highly monodispersed particles tailored to exact target nanometer sizes to optimize light scattering and assay sensitivity.
- Exceptional batch reproducibility: Advanced emulsion polymerization ensures lot-to-lot consistency for stable clinical test kits.
- Outstanding shelf stability: Demonstrates excellent colloidal dispersion stability with zero self-aggregation for up to 24 months in cold storage.
- Flexible pairing: Seamlessly pairs with MPC-based hydrophilic polymers for enhanced blocking and sensitivity improvements.
Performance Attributes:
- Displays extremely uniform spherical shapes with a coefficient of variation of less than 3%.
- Features remarkable long-term colloidal stability, extending up to 24 months in cold dispersion.
- Delivers swift and clear agglutination reactions with minimized non-specific background noise.
