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