The SNAP-Capture Magnetic Beads are used to selectively immobilize and magnetically separate a SNAP-tag fusion protein from solution using magnetic agarose beads. They are prepared by the coupling of SNAP-tag® substrate benzylguanine with highly stable 20-100 µm superparamagnetic particles.
There are two steps to using this system: sub-cloning and expression of the protein of interest as a SNAP-tag fusion, and capture and immobilization of the fusion protein using SNAP-Capture Magnetic Beads.
For larger volume requirements, customized and bulk packaging is available by purchasing through the OEM/Bulks department at NEB. Please contact firstname.lastname@example.org for further information.
