Description
Control sensitivity, specificity and stability with various acid content available within AP USA 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. 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.
- For most applications, Opti-Link 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, nor cause proteins to desorb from particle surfaces
- Various surface acid concentrations available to help optimize reagent development efforts
- Opti-Link 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.
