SNAP-Capture products are agarose or magnetic cellulose beads coupled to a benzylguanine substrate, used to selectively capture and immobilize SNAP-tag® fusion proteins from solution. These beads have a high loading capacity for SNAP-tag fusion proteins and show very low non-specific absorption of proteins from a complex lysate, making them suitable for pull-down applications.

SNAP-tag® is a registered trademark of New England Biolabs, Inc.
