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