Magnetic beads can be used as solid support phase in DNA extraction and purification protocols by a simple bind/wash/elute principle. The products in this category are intended for own development of protocols and are suitable for various sample sources and buffer systems. MagSi-beads for genomic applications are available with a range of physical properties and a silica or carboxyl modified surface.
MagSi-DNA COOH 300 mg/ml, for molecular biology
Carboxylated magnetic silica beads of 300 nm size with optimized magnetic content and long suspension time. Ultra-fast ferromagnetic silica particles with instant magnetic separation. Intended for nucleic acid isolation from various sources (blood, cells, bacteria etc.) for manual and automated work-flow. Under specific conditions, the carboxylated surface enables higher yield and purity from samples.

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||300 ±15 mg/ml|
|DNA yield (20 µl beads)||>3 µg|
