Glutathione Magnetic Beads

Magnetic bead peptide pulldown

Faster Magnetic Response; Simpler Protocols;

LifeTein provides a series of magnetic beads for any bioseparation application, from microliter scale to liter scale. Our Magnetic Beads are nano-superparamagnetic beads covalently coated with highly functional groups or compounds such as maleimide, primary amine, NHS (N-hydroxysuccinimide), carboxylic acid, purified streptavidin, protein A, reduced glutathione, nickel-charged nitrilotriacetic acid, and groups for DNA/RNA purification.

Glutathione Magnetic Beads are nano-superparamagnetic beads coupled with reduced glutathione. With a fast magnetic response rate, high protein binding capacity and low non-specific binding, the product provides an efficient and reliable method to purify GST (glutathione-S-transferase)-tagged fusion proteins from crude cell lysates.


Product Features:

Magnetic Separation – Fast response, complete purification process within 30 min, no chromatograph, no centrifugation, maximally preserve protein activity; Excellent Suspension Ability – Nanometer scale, rapid conversion from solid-phase to solution and vice versa; High Binding Capacity – efficient coupling, higher binding surface area; Low non-specific Binding –hydrophilic microspheres, low non-specific binding; Fully compatible with automation and LC-MS/MS analyses.
