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.|
|Bead number||1-3 x 109 beads/ml|
|Assay (Iron oxide)||≥55 %|
|Binding capacity (biotinylated fluorescein)||0,7-1,2 nmol/mg|
