GE Healthcare has launched Streptavidin Mag Sepharose magnetic beads and the Magrack Maxi rack to offer simplified handling for enrichment of target proteins and purification of biotinylated proteins.
The Streptavidin Mag Sepharose magnetic beads have a high binding capacity for efficient purification of biotinylated biomolecules and enrichment of target proteins.
The magnetic beads are said to provide simplified handling, as rapid capture is facilitated by magnetic devices while delivering scalability and high yield, from low microlitre to high millilitre scale sample volumes.
Streptavidin Mag Sepharose beads support reliable sample preparation for downstream analysis and have a more than 400-fold enrichment factor to enable an increased identification rate of target proteins.
The magnetic beads are hydrophilic with a high density to ensure the beads do not aggregate, so avoiding sample loss and increasing yield.
They are available in two pack sizes: two lots of 1ml and five lots of 1ml.
In addition, GE Healthcare has launched the Magrack Maxi magnetic rack, which is designed to provide easy handling and supports sample capacities of up to 50ml, to provide capture of low-expressed target proteins from larger sample volumes.
Magrack Maxi is a direct scale-up of the Magrack Six, used for small-scale purification.
It consists of an anodised aluminium housing with a detachable plastic bar containing a neodymium magnet, one 15ml tube, and one 50ml tube can be placed in the rack.
