- Bead size: 30 μm
- Matrix: 6% cross-linked agarose
- Filling quantity: Delivered as a 25% suspension
- pH Stability: 3 to 12
- Stabilities: 1 M sodium acetate, pH 4.0, or 6 M guanidinehydrochloride, organic solvents (e.g., 70% (v/v) ethanol), 1% (w/v) SDS, 0.1 M NaOH, 0.1 M HCl
The pairing of an enzyme to its substrate is one of the most specific combinations in life sciences. PureCube Glutathione MagBeads is a suspension of tiny 30 µm magnetic purification beads that are used for this purpose. Their small size provides high mechanical stability. Additionally, we offer GST-tag affinity MagBeads with a bead diameter of 90 µm for very viscous cell media. Alternatively, Glutathione Agarose resins for FPLC or batch spin approaches are also available.
