The μMACS and MultiMACS GFP Isolation Kits facilitate the isolation of GFP fusion proteins from different sources. The super-paramagnetic μMACS MicroBeads included in the kits are conjugated to an anti-GFP monoclonal antibody, enabling fast and effective magnetic labeling of GFP-tagged fusion proteins. The protocol allows for protein isolation within just 1.5 hours. No centrifugation or buffer removal steps are required.
