OptiLink* Carboxylate-Modified Particles

Thermo Scientific* OptiLink* carboxylate-modified particles contain carboxylic acid groups for covalent coupling and can be used in a variety of applications.
The various acid content available within the Opti-Link product line enables you to control such important parameters as sensitivity, specificity and stability. For most applications, Opti-Link particles can be used directly from the bottle without any pre-cleaning. Our proprietary anionic surfactant does not interfere with the binding of proteins, nor cause proteins to desorb from particle surfaces. Various surface acid concentrations are available to help optimize reagent development efforts.

Parking area combines surface area and acid content to give you the surface acid distribution that is useful for assay optimization. The surface area per gram of a particle varies inversely with the particle diameter. Acid content refers to the titrated milliequivalents per gram (mEq/g) and is weight-based.

  • Proprietary anionic surfactant does not interfere with binding of proteins nor cause proteins to desorb from particle surfaces
  • Various surface acid concentrations available to help optimize reagent development efforts
  • OptiLink particles have been used in and are equally successful in molecular biology and research applications
Parking Area Properties

  • Low Acid Content—60–100 Parking Area—Hydrophobic surface, more colloidally stable than plain polystyrene
  • Medium Acid Content—35–59 Parking Area—Hydrophobic and hydrophilic areas; good colloidal stability and good covalent coupling
  • High Acid Content—10–34 Parking Area—Hydrophilic surface; excellent colloidal stability; excellent covalent coupling

Storage Conditions: Store at 2° to 8°C.

Recommended for: Clinical diagnostics, molecular biology, nephelometric, turbidimetric and slide agglutination assays
When using OptiLink 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.
