The Sera-Mag Carboxylate-Modified E3 Beads, 1000 mL (44152105050450) are carboxylate-modified magnetic particles supplied for covalent coupling and magnetic separation workflows. This 1000 mL Sera-Mag E3 format uses 1 µm nominal magnetic beads supplied at approximately 5% solids, equivalent to 50 mg/mL.
Key Features
- Carboxylate-modified E3 bead surface, suitable for covalent attachment and direct binding workflows involving molecules with amino groups
- 1 µm nominal bead diameter, supporting magnetic bead workflows in protein, nucleic acid, and assay development applications
- Approximately 5% solids suspension, supplied at 50 mg/mL for controlled bead dosing
- Original Sera-Mag construction, using a single layer of magnetite rather than the dual magnetite layer used in SpeedBeads
- Approximately 40% magnetite content, with particle density listed at approximately 1.7 g/cm³
- 0.05% sodium azide additive, supplied as part of the bead formulation
- 1000 mL pack size, suited to larger-scale assay development, production, or routine bead preparation requirements
- Refrigerated storage requirement, specified for storage at 2 to 8 °C when not in use
Benefits
- Supports covalent coupling of proteins, peptides, oligonucleotides, and other amine-modified ligands.
- Provides a larger-volume format for laboratories scaling established magnetic bead workflows.
- Helps streamline magnetic separation compared with non-magnetic solid phase workflows.
- Can be used in conjugation, affinity purification, pull-down, nucleic acid isolation, purification, and NGS size selection workflows.
