The Sera-Mag SpeedBead Carboxylate-Modified Beads, 3 µm, 100 mL (29730063) are carboxylate-modified magnetic particles for covalent coupling of target molecules. These 3 µm SpeedBeads have carboxylic acid groups on the surface and are supplied as a 100 mL suspension for protein enrichment, nucleic acid isolation and immunoassay workflows.
Key Features
- Carboxylate-modified magnetic bead surface, with available carboxylic acid groups for covalent coupling
- 3 µm SpeedBead format, with a verified mean bead diameter of 2.95 ± 0.25 µm
- Double coating of magnetite, supporting fast response to an applied external magnetic field
- Cauliflower-like surface morphology, increasing available surface area for binding interactions
- EDAC-compatible coupling chemistry, allowing amine-containing ligands to be attached to the bead surface
- 5% solids concentration, equivalent to 50 mg/mL in suspension
- Purified water suspension medium, containing 0.05% w/w sodium azide
- Refrigerated storage requirement, with handling at 2°C to 8°C when not in use and no freezing
Benefits
- Supports covalent attachment of proteins, peptides and amine-modified ligands for downstream assay development.
- Provides a larger 100 mL volume for established methods, bulk preparation or higher-throughput workflows.
- Helps simplify enrichment workflows by using magnetic separation rather than filtration, chromatography or centrifugation steps.
- Maintains good suspension behaviour in aqueous solution before magnetic separation.
- Suitable for sample preparation, proteomics, nucleic acid isolation and immunoassay applications.
