Summary: Creative Biolabs provides a newly developed method, Bacterial Two-hybrid (B2H) System, for studying protein-protein interactions from both prokaryotes and eukaryotes. The bacterial two-hybrid selection system from Creative Biolabs can not only study interactions of different proteins from both prokaryotes and eukaryotes but also apply successfully in the protein-DNA analysis, and identify antigen-specific single domain antibodies. https://www.creative-biolabs.com/bacterial-two-hybrid-b2h-service.html
