What is phage display?
Phage display is a technique used to study protein interactions by displaying peptides or proteins on the surface of bacteriophages.
How does the affinity selection process work?
Affinity selection involves introducing a phage library to immobilized bait, allowing binding, and then washing away unbound phage.
What are the key steps in the protocol?
The key steps include bait immobilization, phage introduction, washing, and amplification of bound phage.
What types of molecules can be used as bait?
Various proteins or protein moieties can be used as bait in phage display experiments.
What are the applications of phage display?
Phage display can be used in drug discovery, antibody development, and studying protein-protein interactions.
Is phage display suitable for all types of proteins?
While phage display is versatile, some proteins may require specific conditions for successful interaction and display.
