Testing Single Proteins in Many Different Ways
Where is the protein
located in the cell?
Produce lots of
protein for experiment
s.
Turn the protein on and off in mammalian
cells.
Test the protein’s function in
mammalian cells.
What other proteins does this protein
interact with?
Perform assays using protein made in
bacteria.
