Summary: The two-hybrid system is a very powerful molecular genetic tool which investigates protein-protein interactions in vivo. This system can be used to study the interaction between two proteins which are expected to interact or find proteins (prey) that interact with a protein you already have (bait). Creative Biolabs provides a full package of yeast two-hybrid library screening services for quick identification of novel binding partners for membrane or soluble proteins. https://www.creative-biolabs.com/custom-yeast-two-hybrid-screening-service.html
