The Sera-Mag SpeedBead E7 Carboxylate Beads, 100 mL (45152105050350) are carboxylate-modified magnetic particles supplied as a 100 mL pack. These SpeedBead magnetic particles have a nominal 1 µm diameter and a double layer of magnetite for fast magnetic response. They are designed for covalent coupling of biomolecules through surface carboxylic groups using carbodiimide chemistry.
Key Features
- SpeedBead magnetic particle format, using a double layer of magnetite for rapid magnetic response
- Carboxylate-modified surface, with carboxylic groups for covalent coupling using carbodiimide chemistry
- Nominal 1 µm particle diameter, supporting consistent handling in magnetic separation workflows
- Approximately 5% solids concentration, supplied at 50 mg/mL
- High magnetite content, with approximately 60% magnetite in the SpeedBead format
- Low nonspecific binding, supporting improved assay accuracy
- 100 mL pack size, suitable for laboratories using carboxylate magnetic beads across repeated workflows
Benefits
- Enables covalent coupling of proteins, peptides and other amine-containing target molecules.
- Supports faster magnetic separation where shorter assay times or viscous solutions are important.
- Provides a solid phase support for sample preparation, nucleic acid isolation and immunoassay applications.
- Helps maintain suspension consistency through slow settling behaviour when outside a magnetic field.
- Provides a clearly defined 100 mL E7 SpeedBead format for method validation and routine use.
