Specific Application of Silica- and of Carboxylated Beads
| Bead surface | Silica beads | Carboxylated beads |
| Compatible Buffer Systems | Chaotropic buffers | PEG-based, low pH or chaotropic buffers |
| Binding Mechanism | Precipitation with chaotropic salts | Precipitation by polymers like PEG, divalent cations (e.g. Mg2+) or chaotropic salts |
| Elution | Low salt conditions | Low salt conditions or pH shift from acidic to alkalineconditions |
| Recommended use | Recommended in case chaotropic conditions can be applied. | Recommended if flexibility in buffer systems is necessary or if non-chaotropic conditions have to be applied. Results in higher purity and recovery rate under non-chaotropic conditions. |
| Concentration | 10±0,5 mg/ml |
| d50 | 2,4-3,6 µm |
| Bead number | 1-3 x 109 beads/ml |
| Assay (Iron oxide) | ≥55 % |
| Binding capacity (biotinylated fluorescein) | 0,7-1,2 nmol/mg |
