Our Analysis Methods in Peptide-Peptide/Protein Interaction Detection

• Yeast Two-Hybrid (Y2H) Assay: This technique involves the use of two hybrid proteins, one consisting of a DNA-binding domain (DBD) fused to a bait protein and the other consisting of an activation domain (AD) fused to a target protein. Interaction between the bait and target proteins leads to reconstitution of a transcriptional activator, resulting in the activation of reporter genes.
• Co-immunoprecipitation (Co-IP): In this method, target proteins are immunoprecipitated using specific antibodies, along with any interacting peptides or proteins. The immunoprecipitated complex is then analyzed using techniques like western blotting or mass spectrometry to identify the interacting peptides or proteins.
• Surface Plasmon Resonance (SPR): SPR measures changes in the refractive index at the surface of a sensor chip when the target protein or peptide binds to the immobilized bait protein. This real-time technique provides information about binding kinetics, affinity, and specificity of the interaction.
• Pull-down Assay: This assay involves the immobilization of bait proteins or peptides on solid support, such as beads or magnetic particles. The bait proteins are then incubated with a complex protein mixture, and the interacting peptides or proteins are selectively pulled down and identified using techniques like mass spectrometry or western blotting.
