The µMACS FactorFinder Kit facilitates the isolation of virtually any transcription factor from eukaryotic cells, prepared cell lysates, or protein solutions which either directly binds to DNA or forms a complex with other DNA-binding transcription factors. Based on the renowned MACS Technology the µMACS FactorFinder Kit offers a rapid and convenient procedure to isolate high-purity transcription factors. The protocol allows for the isolation of transcription factors in just 1.5 hours. No centrifugation or buffer removal is required.
