I Overview
A spherical magnetic matrix (superparamagnetic agarose composite) with a dynamic binding capacity of 25 µg human IgG/mg beads. Supplied as bulk resin.

| Bead size | 30 (d50 volume-weighted)µm |
| Format | bulk-resin |
| Performance | |
| Dynamic binding capacity | 25 (batch binding, polyclonal hIgG, 30 min at room temperature)µg human IgG/mg beads |
| Ligand leakage | 20 (ELISA)ng/mg IgG |
| Buffers & maintenance | |
| Binding buffer | PBS pH 7.4, 0.05% Tween-20 |
| Elution buffer | 0.1 M glycine-HCl pH 2.5 to 3.0, neutralize immediately with 1 M Tris-HCl pH 8.5 |
| Storage buffer | PBS with 0.02% sodium azide, 2-8 °C. Do not freeze: freezing cracks the beads. |
| CIP | Not suitable for caustic clean-in-place. Wash between steps in binding buffer and treat beads as single-use for immunoprecipitation, where carry-over between samples matters more than bead cost. |
