OptiBind Polystyrene Sulfate Particles

OptiBind® Polystyrene Our production does not utilize common surfactants (like SDS, Tween 20, Triton X-100) that can interfere with protein binding to particle surfaces. Polystyrene surfaces are very hydrophobic and adsorb proteins almost instantaneously. Our proprietary anionic surfactant does not interfere with the binding of proteins nor cause proteins to desorb from microparticle surfaces.

Available in a wide range of diameters (from 0.1 µM to 2.5 µM)
No pre-washing
Tight size distribution—CV<2%
Optimized colloidal stability
Shelf-life of 10 years Storage Conditions: Store at 2-8°C.

Recommended for: Clinical diagnostics, molecular biology, nephelometric, turbidimetric and slide agglutination assays
When using OptiBind particles, ask about our Microparticle Reagent Optimization manual, which outlines our reagent development strategy. This manual includes validated binding, coupling and particle reagent optimization protocols.

Sulfate Particles have been optimized for maximum reactivity in many diagnostic applications.
OptiBind Polystyrene particles can be used direct from the bottle, without any pre-cleaning. They can be used in turbidimetric/nephelometric assays, slide agglutination assays, chemiluminescent assays and in clinical diagnostics and molcular biology applications.
