This bait peptide is typically immobilized onto a solid support, such as Streptavidin biotin pull-down assay compatible beads or resins, often through a biotin-attached peptide. For instance, Streptavidin Sepharose beads are commonly employed, with approximately 20 µl of Streptavidin beads per binding assay being a typical starting point. These immobilized peptides then capture their interacting protein partners, or "prey," from a complex biological mixture, such as cell lysates. The captured protein complexes are then isolated through a series of washing steps, followed by elution of the bound proteins for downstream analysisEasy and Rapid Binding Assay for Functional Analysis of .... This process enables the isolation of a protein complex by adsorbing the complex onto beads.Pull-down assays

One of the significant advantages of the peptide pull-down assay is its versatility. It can be adapted to study a wide range of biological questions.
