Thermo Scientific™ Opti-Link™ Carboxylate-Modified Particles
Description
Control sensitivity, specificity and stability with various acid content available within Thermo Scientific™ Opti-Link™ Carboxylate-Modified Particles. Particles contain carboxylic acid groups for covalent coupling and can be used directly from the bottle in a variety of applications.
- Parking area combines surface area and acid content to give you the surface acid distribution that is useful for assay optimization
- 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
- For most applications, particles can be used directly from the bottle without any pre-cleaning
- Proprietary anionic surfactant does not interfere with binding of proteins nor cause proteins to desorb from particle surfaces or cause proteins to desorb from particle surfaces
- Various surface acid concentrations available to help optimize reagent development efforts
- 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
Recommended for:
- Clinical diagnostics
- Molecular biology
- Nephelometric, turbidimetric and slide agglutination assays
Note:
When using Opti-Link 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.
