Streptavidin Aurosphere Superparamagnetic Beads - 800nm

Regular price $454.00

Product description 

The Aurosphere superparamagnetic particles from Magnostics represent a breakthrough in performance in magnetic separation - the magnetization of these particles is 3-5x higher. This means that bioseparations can be performed in seconds with a high level of efficiency, even in viscous solutions like cell lysates. The Streptavidin Aurosphere particles are conveniently coated with a dense layer of silica that make them ideal for the separation of nucleic acids from Lysis Buffers used to collect clinical samples.
